MicroMod is a modular interface ecosystem that connects a microcontroller “processor board” to various “carrier board” peripherals. Utilizing the M.2 standard, the MicroMod standard is designed to easily swap out processors.
Access all the pins (i.e. ATP) of the MicroMod Processor Boards with the SparkFun MicroMod ATP Carrier Board. In addition to the pins broken out, two separate Qwiic-enabled I2C ports allow you to easily daisy chain Qwiic-enabled devices. A USB-A connector is provided for Processor Boards that have USB Host support.
