KVM-A8
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
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.
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
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:
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 reboot before next step sudo hwclock -w #Read the time of DS1307 sudo hwclock -r ro
Enable OLED display
Run the following command in web terminal window to enable OLED display:
rw systemctl enable --now kvmd-oled ro

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. Maybe it is the problem of Pikvm OS itself, and needs to be resolved by PiKVM.
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: How to enable OLED?
A: Run the following command to enable OLED display:
rw systemctl enable --now kvmd-oled ro
Q: Why OLED is not display?
A: Please confirm that your OS is right:
Q: How to enable RTC?
A: Firstly, insert the C1220 button battery. run the following command:
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 reboot before next step sudo hwclock -w #Read the time of DS1307 sudo hwclock -r ro
Q: Why PiKVM-A3/A4 does not show the video?
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.
