Installing the CPU Module
The IP402 board supports COM Express Type6 CPU module such as the
ET930. Below is a picture showing how the CPU module and the
heatsink should be installed on the IP402 baseboard. There are five holes
on the IP402 that can be used to screw the three parts together – the
heatsink, the CPU module and the baseboard.
