lcd touch screen 褝褌芯 pricelist

I bought this screen because I am making a network packet sniffer with a Raspberry Pi (RPi) and want it as portable as possible. My first thought when I opened it today was that this will certainly be better than the 3.5" unit I got. Don"t get me wrong, that little screen is nice for some things (I"m going to make a portable media player with it for the car), it just didn"t meet my needs for this project like I"d hoped it would.

At 1280x800 native resolution, this is a good high-res screen that displays Wireshark much better than the 3.5" unit. It even displays 1920x1080 (Full HD), though it"s a touch distorted and not quite as clear. That"s to be expected of any screen when it"s adapting an image that isn"t its native resolution. It also displays resolutions smaller than its native, stretching them to fit the entire display area. Depending on the resolution in question, of course, that means the image may be distorted as well.

As an IT professional and an electrical engineer, I found it fun to put together, though some people might not. I love that it can be used with any device that has an HDMI output, and that the touch is sent via USB, making the touch feature usable on any computer, not just the RPi line. It requires no drivers, either, so it works with a large number of operating systems and installation is a breeze - it"s plug and play.

The screen is powered by an included 12 Volts DC power supply. If you are using it with a single-board computer that is powered by a USB 5-Volt power supply, like the RPi, it will power that for you as well - no need for a separate power supply to power your RPi. It also has a power button on it that operates both the screen and the USB power outlet, so that button turns everything on and off together. The only down side of this feature is that the port is only able to deliver 2 Amps of current instead of the 2.5 Amps (in Wattage terms, that"s 10 Watts instead of 12.5 Watts) that the Raspberry Pi Foundation recommends for the model 3 B / 3 B+. I haven"t found that this is a problem, but if you are going to build a hardware circuit project that will push the RPi to its power limits, you"ll need to use a separate power supply for the RPi itself. When my RPi 4 B comes in, I"ll see how this does for powering that (the recommended power supply for that is 5 Volts & 3 Amps, or 15 Watts). I expect this will probably do fine unless I try to run a bus-powered USB 3.0 hard drive with the RPi 4 B.

The one thing I am not happy about, and the biggest reason I only gave 4 instead of 5 stars, is the stand to keep the screen upright. Maybe I didn"t read the description carefully enough, but I thought this came with the stand: IT DOES NOT! In the last section of the manual is a link to a file to 3D print the stand if you need it. REALLY?!? How many people have 3D printers? I only know 1, and I"m in the IT industry! The university I teach at has a couple, so I might be able to get someone to print the stand for me, but that"s just ludicrous in my opinion. Fortunately, I"m not bad at woodworking, so I can make a wooden stand / frame for it.

The screen is supposed to come with 7 short standoffs (pre-mounted), 7 medium ones, and 2 long ones. As you assemble the unit, you mount the controller board to 4 of the pre-mounted short standoffs by running the screw-base of 4 of the medium ones through holes in the board into the short ones. You are then supposed to mount whatever single board computer you choose to the other 3 short standoffs with the remaining 3 medium ones in the same way. The position of these 3 short standoffs is adjustable using the 2 included wrenches so that you can mount any of the single board computer systems available (any version RPi, any other "fruit" boards, Libre Computer boards, etc.). The 2 long standoffs are for the opposite end of the screen from the controller to stabilize it as it sits on a table or desk for use.

After the assembly instructions in the manual, there are directions on how to install an on-screen keyboard in Linux (which most single board computers run by default). I"m OK with this - it means I installed the most current version for my board.
