The SparkFun MicroMod Data Logging Board offers a highly customizable, low-power data logging platform using the MicroMod system allowing you to choose your own Processor to pair with the Carrier Board. The Data Logging Carrier Board breaks out connections for I²C via a Qwiic connector or standard 0.1″-spaced PTH pins along with SPI and serial UART connections for logging data from peripheral devices using those communication protocols.

The Data Logging Carrier Board allows you to control power to both the Qwiic connector on the board and a dedicated 3.3V power rail for non-Qwiic peripherals so you can pick and choose when to power the peripherals you are monitoring the data from. It also features a charging circuit for single-cell Lithium-ion batteries along with a separate RTC battery-backup circuit to maintain power to a real-time clock circuit on your Processor Board.
