CN7 and CN8 - SPI host interface

This is the interface where the SPI control and data signals are routed. There are also power and

ground pins on this interface. CN8 is a 2x8 pin header, compatible with the Bridgetek MM900 series

modules. CN7 is a 20-pin FPC connector which can be used to connect to the MCU board through an

FPC cable.
