PiKVM-A3 is a member of the [[PiKVM]] <ref>PiKVM © belongs to https://pikvm.org</ref> family, which supports Raspberry Pi 4 with a matching metal case. '''The PiKVM-A3 is composed of follow parts:''' [[File:IMG20220616171152-970x600.jpg|700px|RPIKVM-A3]]* '''[[X630]]''' HDMI to CSI-2 Board (for video capture)* '''[[X630-A3]]''' HAT Board (for ethernet, cooling, RTC, ATX Control power in etc)* '''[[X630-A5]]''' Adapter Board (it is installed inside the PC case, and it connect the computer motherboard and IO panel cabe of PC case))* '''[[0.96 inch OLED Shield |0.96 inch OLED]]''' (for display, Resolution: 128×64 pixel)* Ethernet Cable (TIA/EIA-568.B connection, and it's ATX control signal cable) '''Note:''' Please use the supplied USB Type-C to USB 2.0 A-Male Cable only. USB-C to USB-A cable only with DATA lines (for keyboard and mouse emulation), Using other cable might cause instability or damage to either the host PC or the Pi. We need to ensure you isolate the 5v connection between the Raspberry Pi and host PC to prevent backpower issues that can cause instability or damage to either the host PC or the Pi. Some PC case may not have HDMI port, you need to use VGA/DVI to HDMI adapter to transfer HDMI port.
