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.


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.

The powerful, low-power processor from Microchip.

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.


First Steps

Quickstart Guide
All you need to know to get started with your new Arduino board.

Suggested Libraries

The keyboard functions enable 32u4 or SAMD micro based boards to send keystrokes to an attached computer through their micro’s native USB port.
The Servo library allows an Arduino board to control RC (hobby) servo motors.
The ArduinoLowPower library allows you to use the low power features of the SAMD21 MCU to minimize power consumption and maximize battery duration.
