Overview
PiKVM-A3[1] is a member of the PiKVM family, which supports Raspberry Pi 4 with a matching metal case.
The PiKVM-A3 is composed of follow parts:
- 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 (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.
Features
- Designed especially for PiKVM ( Raspberry Pi based KVM over IP)
- Fully compatible with PiKVM OS (refer to user manual)
- Control a server and computer using a web browser
- HDMI Full HD capture based on the TC358743 chip
- OTG Keyboard & mouse; Mass Storage Drive emulation
- Hardware Real Time Clock (RTC) with CR1220 coin battery socket
- Equipped with solidstate relays to protect RPi GPIO pins from computer and ESD spikes
- ATX control via RJ45 connector Switch the machine on or off, reset it, and monitor the status of HDD LED & power LED remotely
- Reserves the 10pin SH1.0 connector on X630-A3 for future I2S HDMI audio support
- Reserves the 4pin header & spacers for I2C OLED display

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.
How to Cool
- For use with raspberry pi 4, X630-A3 (PiKVM-A3) equipped with a active cooling fan that cool your raspberry pi;
- For use with raspberry pi 4, X630-A8 (PiKVM-A8 PCIe version) equipped with a active cooling fan that cool your raspberry pi;
- For use with raspberry pi zero 2 w, X630-A4 (PiKVM-A4) allows to use C296 aluminum heatsink with your raspberry pi zero 2 w, but user need to prepare 4pcs M2.5*7mm screws yourself.

Note:
- The X630-A5 adapter board will be install into the PC Case.
- The wire group ① connect to X630-A5 comes from the PANEL of PC Case.
- The black and red wires(wire group ②) come from X630-A5 accessories.
Installation Video

User Manual
OS download: https://pikvm.org/download/
For Raspberry Pi 4, please use PiKVM V3 platform.
PS:
We recommend that you use the 'V3 Pre-Assembled' version, and this image includes OLED display configuration.
But due to different RTC chips, you still need to configure RTC to make RTC work normally, please refer to the following FAQ#Q: How to enable RTC
FAQ
- First of all, we recommend you to get more FAQ information on the official website: official FAQ, or check the following FAQ;
- You can post a issue ticket at Geekworm forum or email to us (support@geekworm.com) and attached your installation pictures or videos to get some help.
- Blog sharing for reference: https://www.andysblog.de/kvm-over-ip-pikvm-als-bausatz
How to login pikvm?
A: Input the XX.XX.XX.XX ip address on the web explorer, then input user: admin, the default password is 'admin' also.
How to switch to root user?
A: run the following command:
su root
Then type the password, the default password is 'root' also.
How to enable OLED display?
A: Run the following command to enable OLED display:
rw systemctl enable --now kvmd-oled ro
How to enable RTC?
A: Firstly, insert the C1220 button battery. run the following command:
pre> rw sudo nano /boot/config.txt #Then change the line: dtoverlay=i2c-rtc,pcf8563 to dtoverlay=i2c-rtc,ds1307 #Test RTC #Display the current time of the Raspberry Pi date #Write the time of Raspberry Pi to DS1307 sudo hwclock -w #Read the time of DS1307 sudo hwclock -r roWhy OLED is not display?
A: Please follow the steps below to check
1. Please confirm that your OS is right:
Due to downloading the wrong firmware, the OLED cannot be displayed. We ALSO made such mistakes during testing.
2. Please check if the order of OLED screen pins is correct, please contact us if it's a wrong pin order;
pi@raspberrypi:~ $ sudo i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- 3c -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- --
3c is a hexadecimal number, it is the I2C address of OLED, if you can’t find this value, please shut down and reconnect X630-A3&OLED and run this command again, If you still can't find the OLED's I2C address, the OLED screen may be damaged.
4. Then run the following command to enable OLED display:
rw systemctl enable --now kvmd-oled ro
I want to control several pc power. Is it possible with one PiKVM-A3 and several x630-a5
A. No, one kit can only control one pc, you can refer to X680
There is a I2S Audio In on X630-A3, does the packing list contain an I2S cable? How to connect it?
A. No contain an I2S cable. We will add the I2S cable soon.
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.
Why the device does not show the video?
- Double-check that the video capture device is connected correctly and tightly. For the CSI bridge, this should be exactly the camera port;
- Some laptops do not output any signal until you switch the output (usually via the FN + and an F5 key on the keyboard).
- Your computer may have turned on sleep mode for the monitor. Move the mouse to turn it off.
