[Overview]

PiKVM (https://pikvm.org/) 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 PiKVM 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.

This PiKVM-A3 kit (pikvm v3 hat) is designed and based on Raspberry Pi 4 Model B.

It also support Raspberry Pi 3 B+ /3B, but since Pi3 without OTG interface, when PiKVM-A3 is used with Pi3, OTG analog keyboard and mouse cannot be used.

The PiKVM-A3 is composed of follow parts:

• 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)

• KVM-A3 Case (optional part, this case is ONLY compatible with raspberry pi 4)

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.

[How to Power PiKVM]

• Power Input: 5.1Vdc +/-5% , ≥3A (Power Via USB Type-C port of X630-A3), Recommend

Note:  DON'T power via raspberry pi's TYPE-C port, because it is occupied as USB OTG.

[FAQ]

Q. There is a I2S Audio In on X630-A3, does the packing list contain an I2S cable? How to connect it?

• No contain an I2S cable.

• PiKVM OS does not support I2S, so it cannot be used yet.

• The 10pin SH1.0 connector is for future I2S HDMI audio support. Once it supported, we will update the product information for detail use.

Q. Why OLED is not display?

1. Make sure the OLED screen pins is correct: GND UCC SCL SDA

2. Make sure you are using Raspberry Pi 4, V3 Platform instead of V2 Platform! This is very important.

3. Run the following command to enable OLED display:

rw

systemctl enable --now kvmd-oled

ro
