SAMD21 Overview - An introduction to the SAMD21 microprocessor. ![]() It's split into a number of pages, including: This tutorial covers, from the ground up, all things ATSAMD21 and the SparkFun Mini and Dev Breakout boards. The Dev Breakout's extra PCB real-estate leaves room for extra GPIO and an integrated LiPo charger. Both boards have similar feature sets - they equip the ATSAMD21G18 with a USB interface for programming and power, then surround it with an RTC crystal, 600mA 3.3V regulator, and a variety of other components. ![]()
