SparkFun SAMD21 Mini Breakout
If you’re ready to step your Arduino game up from older 8-bit/16MHz microcontrollers, the SparkFun SAMD21 Mini Breakout is a great landing spot. The SAMD21 Mini Breakout is a Pro Mini-sized breakout for the Atmel ATSAMD21G18, a 32-bit ARM Cortex-M0+ processor with 256KB flash, 32KB SRAM, and an operating speed of up to 48MHz. This mini breakout provides you with an Arduino hardware option that solves the problems of low storage limits and dynamic memory stack overflows that have plagued the previous iterations of the Arduino family. Yes, the SparkFun SAMD21 Mini Breakout is even fully supported in the Arduino IDE and libraries for the Arduino Zero!The SparkFun SAMD21 Mini Breakout has been equipped with a USB interface for programming and power, surrounded with an RTC crystal, and a 600mA 3.3V regulator. By utilizing the Pro R3’s extra PCB real-estate we’ve been able to leave room for a few extra GPIO pins. We’ve pinned the Mini Breakout to match – as much as possible – our faithful Pr
