This new Arduino Zero board works with no less than an Atmel SAMD21 MCU. This architecture rolls with a 32-bit ARM Cortex M0+ core, enabling the Arduino Zero to far outperform its predecessor.

Specifications of the SAMD21 M0+ Arduino-compatible board : Microcontroller: Atmel ATSAMD21G18A ARM Cortex M0+ Clock speed: 48 MHz Operating voltage: 3.3V I/O pin limits: 3.3V, 7 mA User I/O pins: 25 ...

A 32-bit extension of the platform established by Arduino UNO, the Zero board (Figure 1 below ) is powered by Atmel's SAMD21 MCU, which features a 32-bit ARM Cortex M0+ core. Figuire 1. The Arduino ...
