It consists of a COM-HPC motherboard, a COM-HPC-ALT module that contains the Ampere Altra SoC and DIMM slots, a heatsink/fan and a VGA to HDMI adapter.

The layout of the Front Panel header can be found in the “COM-HPC Server Front Panel Connection - Instruction Guide” document linked to under “Other Documents” at https://www.adlinktech.com/Products/Computer_on_Modules/COM-HPC-Server-Carrier-and-Starter-Kit/COM-HPC_Server_Base?lang=en (direct link: here).
The FAN_0
header doesn't appear to work: the fan never powers on. Use FAN_1
etc. instead.
The ‘COM1’ box header has a pitch of 2mm: a 2mm to 2.54mm adapter cable with a PC RS232 kit should work.
