==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.

===Connection Diagram===
'''1. The PiKVM-A3 is composed of follow parts:'''

[[File:IMG20220616171152-1.jpg|700px|RPIKVM-A3]]
* '''[[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 Shield |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:'''

:<span style="color:red;">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) and no power supply, 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, but VGA to HDMI adapter may not be compatible with PiKVM-A3

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.

===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 Platform 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.

5. Blog sharing for reference: https://www.andysblog.de/kvm-over-ip-pikvm-als-bausatz

===Enable RTC ===
<span style="color:red;">Only need to configure the RTC function for the X630-A3 V1.5/V1.3/V1.2 version, X630-A3 V1.6 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 '''CR1220''' 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.
'''
