Main & Function Boards Come to MicroMod

Two new types of boards join the MicroMod line for a more customized build!

Favorited Favorite 0

Today, we're adding two new types of boards to the MicroMod product line that will allow you to better customize a project for non-I2C based peripherals with out any soldering whatsoever! Function Boards provide more specific purposes than Carrier Boards while being able to be hot-swapped based on what you need for your project. Meanwhile, Main Boards allow you to host Processor Boards and up to two Function Boards (depending on the Main Board) while still allowing you to connect USB-C, Qwiic, and a LiPo battery. Don't worry, everything still operates with the tried and true M.2 standard that MicroMod has been using since day one, so all of the Processor Boards you already own will still work with these new Main Boards. To make it even easier, all Function Boards utilize the same M.2 standard. Let's jump in and take a closer look.

Meet the new MicroMod Main and Function Boards!

SparkFun MicroMod Main Board - Single


SparkFun MicroMod Main Board - Double


These MicroMod Main Boards are specialized Carrier Boards that allow you to interface a MicroMod Processor Board with either one or up to two MicroMod Function Boards. With the M.2 MicroMod connector, connecting your Processor and Function Boards is a breeze. Simply match up the key on your board's beveled edge connector to the key on the M.2 connector and secure the boards with screws.
