* Control up to 4 USB HDMI computers/servers remotely over an IP network or the internet
* Full remote BIOS level control access the BIOS, and have full control over the keyboard and mouse
* Raspberry Pi Compute Module 4 CM4
* A minimum 16 Gb class 10 memory card is recommended.（In fact, you don't need Micro SD card if you use CM4 with eMMC, because you can flash the firmware into the eMMC.）
'''ATX Conrol cable(Not included):'''
You can make your own ATX control cable, in fact, it is a normal Ethernet cable, and the requirements must be '''568B''' line sequence
