The SparkFun Qwiic Micro at its core is the powerful and versatile ATSAMD21E18, which is an ARM Cortex M0+, 32-bit microcontroller, with 256KB of flash memory that can run at up to 48MHz! It has 12 digital pins which include 5 analog pins, SPI, I²C, and an additional UART data bus as well as a Qwiic connector for easy integration into the Qwiic ecosystem and I²C prototyping.

On the underside of the Qwiic Micro, we’ve left open pads for a LiPo Battery connector that you can add yourself, if you wish you can make the micro-controller portable. We’ve also provided pads on the underside for a flash memory chip to maximize the board’s memory capacity. The SparkFun Qwiic Micro comes programmed with a UF2 Bootloader making it easy to program with easy driver installation!
