SparkFun Qwiic Micro SAMD21 Development Board

SparkFun Qwiic Micro SAMD21 Development Board features an ATSAMD21E18 Arm® Cortex®-M0+ 32-bit microcontroller with 256KB of flash memory. The board is molded to fit SparkFun's standard 1" x 1" Qwiic Connect System standard size and can run up to 48MHz. The board has 12 digital pins (including five analog pins), SPI, I²C, and an additional UART data bus. Micro SAMD21 Development Board also has a Qwiic connector for easy integration into the Qwiic ecosystem and I²C prototyping. SparkFun Qwiic Connect System is an ecosystem of I²C sensors, actuators, shields, and cables that make prototyping faster and less prone to error. The underside of the board has pads for a LiPo battery connector and a flash memory chip. Qwiic Micro SAMD21 also includes a UF2 Bootloader, providing easy programming with a driver installation.
