Zero

by Arduino

Image of Board

The Arduino Zero is a simple and powerful 32-bit extension of the platform established by the UNO. The Zero board expands the family by providing increased performance, enabling a variety of project opportunities for devices, and acts as a great educational tool for learning about 32-bit application development.

The Zero applications span from smart IoT devices, wearable technology, high-tech automation, to crazy robotics. The board is powered by Microchip’s SAMD21 MCU, which features a 32-bit ARM Cortex® M0+ core.

Absolute Newest

Every time we commit new code to CircuitPython we automatically build binaries for it. They are stored on Amazon S3 by language (some which may be unreleased.) Try them if you want the absolute latest and are feeling risky.

Past Releases

All previous releases are available on GitHub. They are handy for testing but we recommend the latest stable otherwise.
