Introduction

MicroMod is a compact interface to connect a microcontroller to various peripherals. You can generally think of the MicroMod system as a ‘brain’ plugging into a ‘carrier board’.

Processor inserted into the Carrier Board M2 Slot

A MicroMod processor board is approximately 22x22mm and can insert into any MicroMod carrier board. A small screw holds the processor board in place. Whereas the original M.2 standard was designed for swapping out peripherals (user could change one solid state hard drive to a larger one) the MicroMod standard is designed for swapping out controllers (user can start with a powerful processor and then change to a low power controller to extend battery life).
