Which OS version should I use?

Only compatible with KVM V3 OS.

Why does the KVM-A3 fail to display video and only show “No Signal”?

Please check the hardware connections, Hdmi cable, X630 output, video service status, laptop display settings, and sleep mode, and refer to the KVM-A3 WiKi for more FAQs.

Why is the OLED not displaying?

Please confirm that you are using the correct OS version(KVM V3) for your Raspberry Pi 4. If the wrong firmware is installed, the OLED will not display. We also encountered this issue ourselves during testing.

Which pins are available on the KVM-A3?

You can only use GPIO16, 26, 11, 17, 25, 9, 10 pins on KVM-A3.
