Zero

Arduino Zero is a simple and powerful 32-bit extension of the platform established by the UNO. This board aims to provide a platform for innovative projects in smart IoT devices, wearable technology, high-tech automation, crazy robotics, and much more.

Main Features

The board is powered by Atmel’s SAMD21 MCU, which features a 32-bit ARM Cortex® M0+ core. One of its most important features 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 and bootloader programming.

Datasheet

Embedded Debugger (EDBG)

The Zero comes with a built-in debugger, which can be used directly with the Arduino IDE 2.0 version to debug programs.

Battery Connector

The Arduino Zero features a barrel plug connector, that works great with a standard 9V battery.
