Sipeed NanoKVM-PCIe IP-KVM Remote Control Operations Maintenance Server, DDR3 RISC-V Linux Development Board, 1TOPS NPU 1GHz SG2002 RISC-V CPU, HDMI PCIe 100M Network Port (NanoKVM-PCIe ETH+WiFi+PoE)

I've needed a out of band IPMI/BMC setup for two office PC's at a rural remote office in order to assist in troubleshooting when they go down or don't come back from Windows updates.I was happy to discover the NanoKVM in some YouTube reviews (Linus Tech Tips) and decided I should investigate one of the NanoKVM variants. I wanted the all internal option so I chose the PCIe+PoE version. Setup was EXTREMLY simple and should be for anyone who builds PCs.The box included the PCie card, HDMI cable, two USB A to C cables, and provided pin header cables. The card size is a really small PCIe x1 size card and is built really well overall. It doesn't feel cheap or like some second rate knockoff part.I simply removed the power, reset buttons and power and led light cables from the motherboard header. I then plugged them into the passthrough pins on the NanoKVM and used the provided cable to route right back over to the motherboard header. This functionality works flawlessly via the NanoKVM portal. Speaking of which, I connected a Cat6 cable and the Nano KVM was discovered on the network after a quick IP scan.The control panel is simple, very basic and this is most likely because their software is still in active development. Reaction time/speed has a tiny bit of lag, but not really any different from Dell's iDRAC on servers. After it was installed I upgraded the latest version of the software and flashed the SD card on the PCIe card to the latest version to address some issues I had, but unfortunately that didn't resolve those.The reason for 4 stars is not because the unit doesn't work, it's because the software has a ways to go in development. The first issue I had was that this card is connected to a desktop PC with 3 monitors setup. Initially when logging in the remote screen was void of any icons and the taskbar was empty. I had no way to see my primary monitor and thus not able to control the system!I discovered in troubleshooting, Windows adds the NanoKVM as an additional monitor. In my case this was 'monitor' #4. I decided to replicate monitor 1 to monitor 4 and that resolved my issue of not seeing my primary monitor in the web control panel.The second outstanding issue is that the KVM only supports a single monitor in it's remote panel. I would thoroughly enjoy it if it could somehow support three monitors, but that is a minor gripe.The last, but probably biggest remaining bug is that I can only sometimes access my motherboard BIOS remotely. It appears with my monitor setup above, I can only access the BIOS/POST screens if I do a clean reboot/restart of Windows. But if the PC was powered off and I had to remotely power it on and see the POST/BIOS screens, it doesn't. Most likely because at that point in the initial hardware boot, it's not considering this as a primary monitor.I am going to see about ordering an HDMI splitter (1 in - 2 out) and connect the KVM nano to the splitter with the primary monitor sharing the other HDMI port to do more of a hardware 'sharing' to see if that allows me to access the BIOS remotely.Overall, this just needs more polishing, but is still VERY usable in a production environment.I have other PC's in this remote office but I may try JetKVM or one of the others to see how their products are.

Received the NanoKVM PCIe earlier than promised, but after installing it per instructions it won't acquire an IP address and the oled display stays dark. I get a green led on the back that blinks a few times and the switch shows link up. Nothing else. I've posted issues on their GIThub page and the Maixhub forum, but no response. I've also reflashed the SD card with the latest firmware.Will be sending this back unless I can get some more information in the next 5 days.

These KVM's work well on my home network. After using the first one, I bought more for some of my other computers. I like the ability to remotely control (including power-on and power-off) some of the computers on my network without needing them to be connected to a keyboard and monitor.There's really only one thing that I dislike, resulting in 4 stars instead of 5. The browser display times out after a while, so you can't continue the remote access from an existing screen. There is nothing you can do from that page to restore the connection, except close the page and open a new one. That can be a little frustrating, but not disqualifying. It works well, and is easy to set up and use.I like the mini-display that shows the status of the KVM, making it easy to know if the KVM is running and what it's ip address is. This makes it easy to troubleshoot if something isn't working right.The installation instructions weren't very easy to follow, but the installation materials were complete and it was quite easy to figure out what to do. The manufacturer's website has supporting documentation and information available as well.
