As technology has advanced, the types of ports on computers have also changed for the better. However, that doesn’t mean devices with older connectors and ports are completely useless. You just need the right USB adapters to make them work. One such adapter is the USB to serial converter, which is used for connecting various legacy devices to modern computers. The USB to serial adapter has a USB-A port on one end and a serial port on the other. The serial port is most commonly RS232, which is a standard that dates back to the 1960s. Although RS232 is the most widely used, these adapters can also feature RS485 or RS422 serial interfaces. They include a chip that allows computers to communicate with the legacy hardware device. In general, these adapters are used for connecting devices, such as printers, scanners, modems, scales, and GPS trackers. They are also commonly used with industrial equipment like Point of Sale (POS) systems, barcode scanners, data-gathering sensors, and microcontrollers. An important thing to note about USB to serial adapters is that not all of them are the same. They can vary in terms of supported baud rates, cable types, duplexing capabilities, and more. So, when buying one, you’ll need to consider several factors, like the type of devices you want to connect to, the number of serial ports you need, whether it requires external power, and more.>>>NL2044HD22 battery for Inspired EnergDo you need a driver for USB to serial adapter?
Most USB to serial adapters require you to install the necessary drivers on your computer. However, some of these adapters offer plug-and-play functionality, in which case the operating system uses a generic driver to communicate through the adapter. In such cases, you may not be able to use specific features, such as adjusting the baud rate, without installing the manufacturer-provided drivers. >>>575983 battery for VAIO VWNC71429-SLInstalling the drivers for the USB to serial adapters is fairly straightforward. You first need to visit the manufacturer’s website, search for your adapter model number and download its driver installation file. Then, simply unzip the file, run the installer, and follow the on-screen prompts to finish installing the missing driver. The setup wizard may ask you to reboot the PC to complete the installation. Once you’ve gone through this process, you can use the USB serial adapter by simply plugging it in.All in all, USB to serial adapters are quite easy to use. They help extend the life of legacy equipment and eliminate the need for expensive hardware upgrades.
Logitech has bumped up prices by up to 25% on a bunch of its products, probably because of tariffs on stuff coming in from China. A video breakdown byCameron Dougherty(via9to5Mac) shows that around 51% of Logitech’s lineup is feeling the impact, with an average price hike of about 14%.
For instance, the MX Master 3S mouse has increased by $20 to $119.99, the Pro X TKL keyboard shot up from $199.99 to $219.99, and the K400 Plus Wireless Touch keyboard is now $34.99 after a $7 increase (that’s a 25% jump!).
On the bright side, not everything has seen price increases—the MX Ergo mouse and the G703 gaming mouse are still at their old prices. You might even find better deals on Amazon, which could help balance out those hikes.
These price increases come right after Logitech pulled its financial outlook for 2026, thanks to “tariff uncertainty” tied to President Trump’s trade policies. It hadoriginally predictedsales for 2026 to be between $4.53 billion and $4.71 billion, but is still sticking with its2025 sales forecast.
Experts say Logitech’s pricing often sets the trend for other brands, so we might soon see similar increases from competitors.
In recent weeks, President Trump has announced various tariffs worldwide, leading to much uncertainty worldwide.
Currently, China is facing exceptionally high tariff rates from the Trump administration. These began with a 10% tariff on all imports from China that took effect February 4, 2025, which was then increased by another 10% on March 4.
The tariff situation has escalated significantly, with China now facing up to a 245% tariff on some imports to the United States. This includes a 125% “reciprocal” tariff, a 20% tariff related to the fentanyl crisis, and existing Section 301 tariffs that range from 7.5% to 100% on specific goods.
Unlike other countries that received a 90-day pause on new tariffs above the 10% baseline, China has been excluded from this reprieve. While imports from most other countries maintain the 10% baseline tariff, China’s minimum tariff rate was increased to 145%.
Android users get to rejoice as Google introduces a functionality iOS has had since 2023.
What you need to know
Google Chrome 135 on Android introduces a long-requested bottom address bar feature this week.
The said feature had been available for iOS users since 2023, and other browsers like Samsung Internet have also had this feature for a while.
The latest feature update has been popping up for Chrome on Android this week, and a wider roll out is expected soon.
Google Chrome users will now have an easy way to browse, especially for large-screen phones. The search giant has started rolling out a new update, which shifts the address bar from its conventional top position to the bottom.
According to9to5Google, Google has initially tested the bottom address bar on its Chrome app for Android last October, and the company is now rolling it out to the stable version of the browser app onAndroid phones.
The publication further notes that some users on the stable build, which is the Chrome 135 version, are already seeing the new prompt “You can touch and hold to move the address bar to the bottom.” Alternatively, Chrome settings also has a new section dubbed “Address bar” that allows users to change its placement to top or bottom, per their preference.
Further, aside from the positioning, nothing significantly has changed with the new address bar. The three-dot menu and its options like new tab, incognito tab, bookmarks, and history remain the same, and users would still have to reach for the top of the screen to get them, while having them reordered to the bottom would have been ideal as they are the most used options while browsing.
(Image credit: 9to5Google)The said feature appears to have just started popping up on the Chrome 135 version this week, and the wider roll-out of the feature is expected soon. It has been a widely requested feature as the phones today have become hard to reach to the top, especially when using with a single hand.
Such handy options are already available in browsers like Samsung Internet and Arc browser. It is good to see Google catch up and bring the most requested feature finally to Android devices, whereas iOS users havehad this functionalityfor a while now, since 2023 to be precise.
These combos help you get more done on your Mac with less effort
Keyboard shortcuts give you a significant productivity boost with minimal effort, so they’re worth the time to master whether you’re on macOS or Windows.
I grew up using mostly Windows machines so it took me some time to master keyboard shortcuts on the Mac, but now that I have there are definitely a handful that I use more often than the rest.
With that in mind, I wanted to quickly run down the most useful keyboard shortcuts I think ever Mac owner should use. Even thebest MacBookon the market is limited by how effectively you can use it, and these tips will help you be faster and more productive no matter which Mac you’re using.
After writing ourmacOS Sequoia reviewI’ve also come to really appreciate some of the new window tiling features Apple released in that upgrade, so I’ll share some useful shortcuts for that as well.
This shortcut lets you quickly move the active window to the left, right, top or bottom half of the screen.
I really like to use window tiling in macOS to arrange multiple windows side-by-side so I can do things like keep tabs on work chat while I’m writing a story in another window.
It’s pretty easy to do this in macOS Sequoia or later, as you can just hit theFunction + Control + arrow keyto instantly move the active window into the half of the screen that matches whatever arrow key you hit. So hitting up moves your window in the top half of the screen, hitting left moves it into the left half of the screen, and so on.
Adding Shift to the mix lets you move the second active window to the other half of the screen automatically.
Once you get the hang of moving your active window around the screen with a single key combo, it’s time to get used to moving multiple windows at once.
I really like to use theFunction + Control + Shift + Arrow keyversion because it’s a more powerful implementation of the same key combo that lets you move two windows at once instead of just one.
So when you use this key combo, the active window moves to whichever quadrant of the screen you indicate with the arrow key (up moves it into the top half, right moves it into the right half, etc) and then the second window on your Mac moves into the opposite section of the screen.
This allows you to quickly re-orient your windows with a single keypress so that, say, whatever you’re focusing on is on the righthand side of the screen while the second window on your desktop (say, your video conferencing window) automatically relocates to the opposite side of the screen.
It takes some time to master, but once you get the hang of using this keyboard combo I find it’s one of the most useful in my repertoire.
I use this shortcut all the time because it’s a huge time-saver, especially if you (like me) have a bad habit of keeping 3-6 apps open at once. To switch between open apps on your MacBook, simply pressCommand + Tabto open the switching window and then (while continuing to holdCommand) tapTabto move the cursor between open apps.
Release the keys when you’ve selected the app you want, and it should immediately pop into the foreground of your desktop. If you’re trying to switch to an app that’s minimized to the Dock, it will stay minimized unless you alsopress Optionas you are releasing theTabkey to select the app. If you do it right (it can be finicky) the app should pop off the Dock and open itself before you.
Command + Space: Spotlight Search
I think Spotlight Search might be my most-used macOS keyboard shortcut because it helps me launch apps as fast as possible, without having to hunt around for an icon to click. To use it simply pressCommand + Spaceto bring up Spotlight Search, then type whatever you’re looking for.
Spotlight Search is a great time-saver because it lets you quickly search for apps, documents, emails and more with just a few keystrokes. Once you’ve found the app or file you’re looking for, you just hit one more key (Enter) and it will open right from the Search menu, saving you precious time.
Command + Z/Shift + Command + Z: Undo/Redo
I know this one seems so simple it shouldn’t merit mention, but it’s also so useful that it has to be included. I’m talking of course about Undo and Redo, which work both in macOS and in many of the apps you’ll be using on your Mac.
To undo the last thing you did, just hitCommand + Z.If you change your mind and want to redo the thing you just undid, it’s easy enough — just hitShift + Command + Z.
If you’re lucky, the app you’re using these in will allow you to undo and redo multiple steps backwards or forwards, which can be really useful when you’re editing long documents or doing intensive photo/video work.
Shift + Command + 3-5: Capture screenshots
In the Screenshot app (which I’ve put on the Dock here, but you can also open any time by hitting Shift + Command + 5) you can choose whether you want a screenshot or video recording, tweak the settings and more.
I use this combo all the time, but then I write about screenshots for a living. Even if you don’t need to use it quite as often, being able to capture screenshots of your whole desktop or specific parts of it can be a huge time-saver when you’re trying to show someone what’s happening on your Mac or how to find something.
There are a few key useful keyboard shortcuts for capturing screenshots on Macs. The most important one to know isShift + Command + 3because it will instantly capture a screenshot of your entire Mac desktop, which will then appear on your desktop ready to be used. If you’d rather capture just a portion of the desktop, you can do that by pressingShift + Command + 4and then clicking and dragging a selection box around the area you want to screenshot.
If you want even more granular control over what you screenshot, pressShift + Command + 5to bring up the Screenshot app. From here you can choose to capture a screenshot or video of the whole screen, just a portion of the screen, or a selected app/window. You can also access the Options menu to change details like whether you want a timer on your screenshots, where screenshots are saved and more.
In fact, I use the Screenshot app so often that I just dragged it to my Dock for easy access. If you find yourself using it all the time, I recommend you try the same!
Command + W: Close active window
Master this shortcut and you’ll quickly become an app murderer, obliterating windows that are no longer useful as you burn through your task list. Rather than reaching down to grab your mouse or use the trackpad to click the big red “close app” button, simply pressCommand + Wto close whatever app or window is currently active.
Option + Command + Esc: Force a program to close
Ever have a program that just won’t play nice, and you have to close it? There’s a key combo for that.
If you want to force a program to close you can do so pretty simply by pressingOption + Command + Esc, selecting the app from the list of running programs and hitting theForce Quitbutton (though sometimes it saysRelaunchif the app is something key, like Finder).
This is effectively the macOS equivalent to Alt + F4 onWindows 11, and it’s a good way to shut down a troublesome program that you can’t close by other means.
Ctrl + Command + Q: Lock your Mac
If you’re concerned about coworkers and family members messing around with your machine when you get up to use the bathroom, no worries. You can instantly lock your Mac by hittingCtrl + Command + Q,which is a bit faster and easier than finding and clicking on the appropriate option in the File menu.
This is a good habit to get into if you work in a public area where someone (say, a child or a childish coworker) might be tempted to mess around with your machine while you’re not around.

The Pixel 9a camera is good, but not as good as I’d hoped
TheGoogle Pixel 9ais thebest cheap phoneyou can buy right now, and comes packing an impressive camera. That’s not a huge surprise; theGoogle Pixel 8awas much the same, andGoogle’s mid-range phones often produce excellent photos for their price. The question isn’t whether the Pixel 9a’s camera is good, but rather how much better is it than its predecessor?
ThePixel 9a has a stylish new design, enhanced AI features from the Tensor G4 chipset and even faster charging. But, strangely, Google has actually downgraded the main camera this year. Rather than offering a 64MP sensor like the Pixel 8a, the Pixel 9a has a resolution of 48MP.
While there’s more to photography than extra megapixels, it’s going to be interesting to see how much of an impact this has. So to find out what’s what, we put the Pixel 8a and Pixel 9a through an extensive photo shootout covering 10 different categories.Here’s my verdict on which phone has the better camera.
Daytime
The Pixel 9a may not have as high a resolution as the Pixel 8a, but it still manages to take consistently better photos. I should caveat this by saying that the final products from each device don’t look all that different, but the Pixel 9a manages to come out on top.
While the subject in shot tends to look pretty similar, the Pixel 9a does a much better job of capturing everything around it. That means the background is clearer and much crisper, especially if there’s grass involved. The coloring was also a little bit more true to life, which is always beneficial.
It’s worth noting that the Pixel 9a did a better job of capturing the individual dust particles on myLegosets much more clearly. So if my girlfriend asks, that’s why I haven’t cleaned them in the last… well, ever.
You know how people always complain that phone companies just release the same phone every year? If they were basing that assumption on the Pixel 9a’s ultrawide camera, they’d be right. Because these images are virtually identical — and the only difference seems to be a little deviation in contrast.
I’ve looked over a bunch of shots I took with the 13MP ultrawide camera, and the story is the same every single time. There is no other tangible difference between any of the comparison photos. The actual quality is so similar, that if there are any other key differences my eyes can’t make them out.
I’ll be totally honest here, I can’t really tell the difference between the coloring from Pixel 9a and Pixel 8a either. Once again, the only way I can actually tell them apart is because of the aspect ratio. The Pixel 8a shot in 16:9, whereas the Pixel 8a shot in 4:3.
If I didn’t know any better, I’d assume that all these phones had been taken on the same phone and cropped to size. But they weren’t, and it means that you’re not going to notice any major improvements to color reproduction on the Pixel 9a. Not that the colors are bad, of course.
When it comes to zooming shots, things don’t work out quite so well in the Pixel 9a’s favor. In fact 2x magnification shots on the new phone don’t seem to be that much different from the Pixel 8a. In fact it’s quite difficult to tell the two apart.
The overall image is a little darker, and there is slightly more clarity in long-distance shots, but overall the picture is just not very good.
Pixel 8a:
Even when you push that magnification up to 8x, the maximum both phones allow, and the image quality isn’t any different. I struggled to differentiate the two phones; we’re mostly talking about variations in color, and not much else.
You’d think that the Pixel 8a would do better at long distance shots, on account of it having higher resolution. But this doesn’t seem to be the case. I suppose those are the perils of not having a telephoto lens.
Winner: Tie
Pixel 9a:
Panorama
When it comes to panorama shots, there isn’t really much debate to be had. The Pixel 9a may not take the most crystal-clear shots imaginable, but it’s immediately apparent that it’s doing a better job than the Pixel 8a. Not only are the colors more vivid, but the finer details of the phone are significantly better. Text on signs in the distance is one that particularly stands out to me.
It’s pretty similar to all the other shots. Outdoor panoramas taken on the Pixel 9a pick up a lot more detail than the Pixel 8a, which has a tendency to blur them all together. The colors are significantly more muted with last year’s model, and you can tell it struggles to pick out details in darker areas of the shot.
Winner: Pixel 9a
Photo sequence：Pixel 8a Pixel 9a

Macro
In this macro shot of a vine, I was able to get a lot closer with the Pixel 9a and pick up some of the fibers on the tip of the stem in a lot better detail than the Pixel 8a. That said, the Pixel 8a was able to capture a lot more of the vine itself, including a much sharper look at the spider-silk hanging from the leaf.
Checking some of my other photos and it’s clear that the Pixel 8a does do a great job of macro photography, despite not having a dedicated macro mode. However it seems as though the Pixel 9a is better at close-ups and capturing a sharper image of what’s in the foreground.
Winner: Pixel 9a
Photo sequence：Pixel 9a Pixel 8a

Low Light
At first glance the night time shots of this church don’t look all that different from one another. There’s some extra detail in the clouds from the Pixel 9a, and a little bit more contrast in the coloring of the brickwork, but that’s about it.
Looking a little closer, the clarity just isn’t there on Pixel 9a, with the smaller details looking significantly blurred on both the church tower and the tree to the right. Sensing something wasn’t right, I went to check some of my other photos and it was a slightly different story.
I wouldn’t call the church shot a fluke, since the Pixel 9a does seem to struggle with picking up details on buildings in low light. But for the most part it does seem to offer a better picture when light is at a premium.
Winner: Pixel 9a
Photo sequence：Pixel 9a Pixel 8a

Pixel 8a
Verdict
Overall it’s fair to say that the Pixel 9a does have a better camera, though it wasn’t the slam dunk a lot of people (myself included) had hoped it would be. So, while the Pixel 8a didn’t beat its successor in any single category, the fact that there were so many draws is rather telling.
Particularly since the front and ultrawide lenses seem to be producing the exact same photos on both devices.
This is not to say that the Pixel 9a has a bad set of cameras. It’s still able to produce some pretty consistently good photos, albeit with some inconsistent performance in low light conditions. That said, if you have or are interested in the Pixel 8a, then you won’t be missing out on much in the camera department.
