Geekworm KVM-A3 Kit with Raspberry Pi 4 Case, Compatible with PiKVM ATX HDMI CSI Only for Raspberry Pi 4 Model B (Raspberry Pi Not Included)

This was quick and easy to assemble. I expected to have some issues with it, but it worked pretty much flawlessly. The software is excellent and does way more than I expected. The ability to build a device with this functionality at this price is unbelievable. It works better than commercial KVMs which cost several times more.

This is just a case, you need to buy extra pie to make it work! And you need to know how to install pie in software as well, not for someone new try to assble

Good item

I bought this as I needed remote KVM/IPMI access in an area that I can only get WiFi, and this kit plus PiKVM was a the perfect solution. This was my first foray into PiKVM so I can't it compare to other kits or PiKVM's own product, but this kit had a very easy setup and did everything I wanted. All you need is an RPI4B, this kit (with power supply), a microSD card, and an HDMI cable. Follow the instructions that come with the kit to assemble, then follow the instructions on the Geekworm website to image it with PiKVM, then go to the PiKVM website to finish configuring. If you expect to do some tweaking/experimentation and think you may need to re-image more than once, I suggest you don't close up the chassis. Although there's a slot to take the SD card out through the case it's too narrow to use, so better to leave the case open until you're 100% set up in case you need to remove the card, rather than removing all the screws every time. Once setup and imaged, all the features worked out of the box, including the OLED. It only takes a handful of commands in PiKVM to get it fully functional for immediate use, though there's plenty of tweaking you can do beyond the basics. If you need WiFi I suggest running wifi-menu (the built-in Arch linux wifi setup tool) instead of the instructions on the PiKVM website. You will likely get a repeating error message about low voltage when you first boot PiKVM with this kit attached. This is normal per the PiKVM website and should go away after a few hours of being powered on and building up a charge. It doesn't impact anything beyond being annoying and filling up your screen before you have full monitor resolution. CR1220 battery is not needed but should get rid of it as well. Great product, will probably buy several more in the future.

Quick delivery. Easy to assemble. The documentation wasn’t entirely clear about connecting the ATX wiring part to the PC panel but I figured I out after studying the wiring diagram. It works fine powering on off my old pc. Next going to try it with my KVM and remote manage my little home lab.
