Arduino - Zero 32-Bit ARM Cortex M0+

The Arduino Zero is a simple and powerful 32-bit extension of the platform established by Arduino UNO. The Arduino Zero enables creative individuals to realize truly innovative ideas for smart IoT devices, wearable technology, high-tech automation, crazy robotics, and projects not yet imagined. The board is powered by Atmel’s SAMD21 MCU, which features a 32-bit ARM Cortex M0+ core. The Zero board expands the Arduino family by providing increased performance to fuel the creativity of the maker community. The flexible feature set enables endless project opportunities for devices and acts as a great educational tool for learning about 32-bit application development. One of its most important feature is Atmel’s Embedded Debugger (EDBG), which provides a full debug interface without the need for additional hardware, significantly increasing the ease-of-use for software debugging. EDBG also supports a virtual COM port that can be used for device programming and traditional Arduino boot loader functionality.

The board contains everything needed to support the microcontroller; simply connect it to a computer with a micro-USB cable or power it with a AC-to-DC adapter or battery to get started. The Zero is compatible with all Arduino shields that work at 3.3V and are compliant with the 1.0 Arduino pinout.
