The SAMD21 Mini Breakout is a powerful, compact (Pro Mini-sized) breakout based on Atmel ATSAMD21G18; a 32-bit ARM Cortex-M0+ processor with 256KB flash, 32KB SRAM, and an operating speed of up to 48MHz. This board can be used as a breakout for ATSAMD21G18 controller to explore it's the features. The charm and convenience of Arduino IDE and hardware options makes it an excellent choice, solving the problems of low storage limits and dynamic memory stack overflows that have plagued the previous iterations of the Arduino family.
The onboard micro-B USB Port can be used to power as well as program. One of the most unique features of the SAMD21 is SERCOM a set of six configurable serial interfaces that can be turned into either a UART, I2C master, I2C slave, SPI master, or SPI slave.
