How do you reboot the target machine and stay powered? I know some ipkvm can interface with the ATX header, but that's usually an extra addon. It also requires have some access to the ATC header during installation. I have a tiny "NAS" where the mobo is the size of credit card and very difficult to access. The power supply is external. The USB doesn't stay powered when turned off. I cobbled together a bare NanoKVM running debian, a relay normally closed to interrupt mains power to the target, and a tiny little power supply into a 3D printed case. I have also added a diode so that the ipkvm can also be powered by the target USB for flexibility. Note that the sg200x boots with its pin pulled high with a ~50kΩ resistor (pullup). So you need to pull it down with a 1kΩ resistor. This also renders the system more robust to transient voltages anyways. https://wiki.sipeed.com/hardware/en/kvm/NanoKVM/introduction.html https://wiki.sipeed.com/hardware/en/kvm/NanoKVM/introduction... https://github.com/slcpcom/sophgo-sg200x-debian https://github.com/slcpcom/sophgo-sg200x-debian
