==Overview==
PiKVM-A8 is a member of the [[PiKVM]] <ref>PiKVM © belongs to https://pikvm.org</ref>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
[[File:I2S-Audio-Connector.png|100px]] was added since March 2023!!!

==How to Power==
* POE power (Recommend, but it's expensive because you need a poe switch, '''<span style="color:red;">the poe switch must support 802.3af.</span>''')
* Power Input: 5.1Vdc +/-5% , ≥3A (Power Via USB Type-C port of X630-A8)

==User Manual==
First you need to make sure your hardware connections are correct, please refer to the above video and diagram below.

<span style="color:red;font-weight:bold">'''Important Note:'''</span> 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 [https://files.pikvm.org/images/v3-hdmi-rpi4-box-latest.img.xz PiKVM V3 platform]. <span style="color:red;">Only compatible with '''PiKVM V3 OS''', NOT support '''V4'''</span>

:[[File:Pi4-V3-HAT.png|800px|PiKVM V3 platform]]

3. Flash it to a microSD memory card by following [https://docs.pikvm.org/flashing_os the simple instructions] or [https://www.raspberrypi.com/documentation/computers/getting-started.html#installing-the-operating-system Official installation tutorial]

4. Power the device, then open explore to login the pikvm web ui.

===Enable RTC ===
<span style="color:red;">Only need to configure the RTC function for the X630-A8 V1.7 version, X630-A8 V1.8 don't need.</span>

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 <code>dtoverlay=i2c-rtc,pcf8563</code> to <code>dtoverlay=i2c-rtc,ds1307</code> (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 <code>PiKVM OS V3 Pre-Assembled</code>, the OLED configuration is already pre-installed, you can ignore this step.

===Enable hdmi audio===
Refer to [[Enable pikvm hdmi audio]]
