      KVM ( is a very powerful and Open Source Software which allows for a remote connection via your Raspberry Pi to turn on/off or restart your computer, configure the UEFI/BIOS, and even reinstall the OS using the Virtual CD-ROM or Flash Drive. You can use your remote keyboard and mouse or KVM can simulate a keyboard, mouse, and a monitor, which are then presented in a web browser as if you were working on a remote system directly. It's true hardware-level access with no dependency on any remote ports, protocols or services!

      The KVM refers to Keyboard Video Mouse. The KVM-A3 kit is designed and based on Raspberry Pi 4 Model B, NOT support Raspberry Pi 3B/3B+.

      For Raspberry Pi Zero 2W, pls refer to KVM-A4 Kit.

      For KVM-A8 PCIe version based on Raspberry Pi 4, pls refer to: KVM-A8 Kit.

      The KVM-A3 is composed of follow parts:

      • KVM-A3 Metal Case for Raspberry Pi 4
      • X630 HDMI to CSI-2 Module (for video capture)
      • X630-A3 Expansion Board (for ethernet, cooling, RTC, 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 (for display, Resolution: 128×64 pixel)
      • Ethernet Cable (TIA/EIA-568.B connection, and it's ATX control signal cable)


      • 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.
      • The X630-A1 plate has no use for the KVM-A3 installation, don't need to use X630-A1!!!

      How to Power

      • Power Input: 5.1Vdc +/-5% , ≥3A (Power Via USB Type-C port of X630-A3) [DON'T power via Raspberry Pi's TYPE-C port, because it is occupied as USB OTG.]
