Update History
X630-A8 (The core expansion shield of this kit) was upated from V1.7 to V1.8 in October 2023. But amazon shop still have old version inventory, please ask for the version before purchase if you need new version.
- Support WatchDog
- RTC function can be used directly, no need to configure.
Overview
PiKVM-A8 is a member of the PiKVM [1]family. It only supports Raspberry Pi 4 Model B. It is directly inserted into the computer case as a PCI card. That is, you can put a computer into your computer. It does not require additional cables and is more convenient to use.
The PiKVM-A8 is composed of X630-A8 and X630:
- X630 HDMI to CSI-2 Board (for video capture)
- X630-A8 HAT Board (for POE, RTC, ATX Control power in etc)
Note: There is no I2S Audio In connector on the X630-A8 for the first production batch, the I2S Audio In connector
was added since March 2023!!!
How to Power
- POE power (Recommend, but it's expensive because you need a poe switch, the poe switch must support 802.3af.)
- Power Input: 5.1Vdc +/-5% , ≥3A (Power Via USB Type-C port of X630-A8)
How to Cool
X630-A8 (PiKVM-A8 PCIe version) equipped with a active cooling fan(3007 5V PH2.0) that cool your raspberry pi;

User Manual
First you need to make sure your hardware connections are correct, please refer to the above video and diagram below.
Important Note: If you receive and are using the black 10pin I2S audio cable, the I2S cable maybe in the wrong wire connection. Refer to below photo. Please do not use the wrong I2S cable for KVM-A8, you need to change the I2S cable to right direction to use or attach order number to contact us via email(support@geekworm.com).
OS Download & Installation
1. Firstly, need prepair a micro sd card, a minimum 16 Gb class 10 memory card is recommended.
2. Download an appropriate OS image for the PiKVM, the url link is: https://pikvm.org/download/
- We recommend that you use the 'V3 Pre-Assembled' version, and this image includes OLED display configuration.
- For Raspberry Pi 4, please use PiKVM V3 platform. Only compatible with PiKVM V3 OS, NOT support V4
3. Flash it to a microSD memory card by following the simple instructions or Official installation tutorial
4. Power the device, then open explore to login the pikvm web ui.
Enable RTC
Only need to configure the RTC function for the X630-A8 V1.7 version, X630-A8 V1.8 don't need.
Due to different RTC chips with official PiKVM hardware, you still need to configure RTC to make RTC work normally.
Firstly, insert the C1220 button battery. run the following command in web terminal window:
1. switch to 'root' user
su root
then type the password, and the default password is 'root' also.
2. Switch OS to writable mode
rw
3. Edit the /boot/config.txt file, and change line dtoverlay=i2c-rtc,pcf8563 to dtoverlay=i2c-rtc,ds1307 (due to use the different RTC chip).
sudo nano /boot/config.txt
Then save & reboot the device;
4.Test & setting RTC, write&read the time of Raspberry Pi to RTC DS1307
date sudo hwclock -w sudo hwclock -r
5. Swith OS to readonly mode
ro
Enable OLED display
Run the following command in web terminal window to enable OLED display:
rw systemctl enable --now kvmd-oled ro
If you are using PiKVM OS V3 Pre-Assembled, the OLED configuration is already pre-installed, you can ignore this step.
FAQ

Q. How to do if PiKVM-A8 hangs up and has to be started manually?
A. The PiKVM-A8 hardware itself does not cause the system to reboot, and Pikvm-A8 shield is controled by raspberry pi 4;
Please ensure these keys:
1. The PiKVM OS version is correct;
2. Check & use a high-quality power supply;
3. Whether the raspberry pi 4 temperature is too high;
4. Contact us via email to support@geekworm.com
Q. I want to control several pc power. Is it possible with one PiKVM-A8
A. No, one PiKVM-A8 can only control one pc. Please refer to X680 4-port IP KVM Switch.
Q. There is a I2S Audio In on X630-A8, does the packing list contain an I2S cable? How to connect it?
A. 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: How to login?
A: Input the XX.XX.XX.XX ip address on the explorer, then input user: admin, the default password is 'admin' also.
Q: How to switch root user?
A:
su root #default password is root also
Q: Why PiKVM-A3/A4 does not show the video only display No Signals?
A:
- 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.
- If your desktop only has a VGA display port, there may be no video signal when you use VGA to HDMI adapter, and there is no way to solve this; However, you can try to lower the resolution and restart the PC to test, but the probability of success is very low.
