List of Arduino boards and compatible systems

This is a non-exhaustive list of Arduino boards and compatible systems. It lists boards in these categories:

Released under the official Arduino name
Arduino "shield" compatible
Development-environment compatible
Based on non-Atmel processors

Where different from the Arduino base feature set, compatibility, features, and licensing details are included.

Official

Many versions of the official Arduino hardware have been commercially produced to date:

Superseded

The following have been superseded by later and more capable versions from Arduino.

Compatible

Although the hardware and software designs are freely available under copyleft licenses, the developers have requested that the name "Arduino" be exclusive to the official product and not be used for derivative works without permission. The official policy document on the use of the Arduino name emphasizes that the project is open to incorporating work by others into the official product.
As a result of the protected naming conventions of the Arduino, a group of Arduino users forked the Arduino Diecimila, releasing an equivalent board called Freeduino. The name "Freeduino" is not trademarked and is free to use for any purpose.
Several Arduino-compatible products commercially released have avoided the "Arduino" name by using "-duino" name variants.

Footprint-compatible

The following boards are fully or almost fully compatible with both the Arduino hardware and software, including being able to accept "shield" daughterboards.
