RedBoard Logo

Ever since we made the first RedBoard in 2013 we've continued to tweak, improve upon, and introduce new RedBoards all with the familiar UNO footprint.

SparkFun RedBoards


Sketch above is meant to show general dimensions of RedBoards. Some board dimensions may differ slightly.

Arduino Compatible

As you would come to expect out of an Arduino UNO alternative, all SparkFun RedBoards are compatible with the Arduino IDE.

Consistent Footprint

Commonly known as the UNO footprint, SparkFun's RedBoards take advantage of this familar form factor to be compatible with many of the shields on the market today.

Abundant Options

There's a RedBoard for everyone. Whether you need the power of the onboard SAMD21 of the RedBoard Turbo or the battery conservation of the RedBoard Artemis we've got an option for your next build.
