SparkFun MicroMod Main Board - Double

Description Attachments

The SparkFun MicroMod Main Board - Double is a robust carrier board that allows seamless integration of a MicroMod Processor Board with up to two MicroMod Function Boards. The board uses an M.2 MicroMod connector, ensuring easy and secure connection of your Processor and Function Boards. This is done by matching the key on your board's beveled edge connector to the key on the M.2 connector and securing the boards with screws.

The Double Main Board comes equipped with one USB-C connector for power and programming of the Processor Board. The board also has a jumper at the back that can isolate the USB C's shield pin. It features two buttons for reset and boot. The Processor Board pins are also broken out as 2x5 SWD pins. The board includes a 2A resettable fuse and a 3.3V/1A voltage regulator. Additionally, it has a second 3.3V/500mA voltage regulator to power your Qwiic-enabled devices. The board also includes PTH jumpers for advanced users who want to bypass the fuse and measure the current consumption on the 5V and 3.3V lines for low-power testing. The board also includes a 2-pin JST connector and a single-cell LiPo MCP73831 charge IC (set to a charge rate of 500mA).

The board features two switches that can toggle between the general-purpose pins and each Function Board's voltage regulator. It also includes a third switch to switch between different SPI chip select pins on the second Function Board. Four status LEDs are available for power and charging, and these can be disabled through the jumpers. The board also features a microSD card socket for data logging, which can be disabled through the I/O pins. Lastly, the board includes two Qwiic connectors with built-in pull-up resistors to conveniently add Qwiic-enabled I2C devices to your projects.

Please note that a MicroMod Processor and Function Boards are not included with the MicroMod Main Board and will need to be purchased separately.

The 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 and function boards on the fly. Pair a specialized carrier board for the project you need with your choice of compatible processor.
