Installing the CPU Module
The IP510 board supports Nano ETX COM Express CPU module such
as the ET830. Below is a picture showing how the CPU module and the
heatsink should be installed on the IP510 baseboard. There are five holes
on the IP510 that can be used to screw the three parts together – the
heatsink, the CPU module and the baseboard.
