The Arduino Tre is a pretty cool piece of kit combining a Linux system with the Arduino pinout. Care to take a guess at what the next Arduino board will be called? The Arduino Zero, obviously.

Arduino pinout for Arduino UnoI myself own an Arduino Uno R3 and found that it can simplify my projects development and microcontroller programming, but sometimes I need to know the Arduino pinout.

Also on board is the Atmel SAM3X8E – the same chip in the new Arduino DUE – and has pinouts for all those Arduino shields you have lying around.
