Like the Nano, the Micro's size and male pin headers make it perfect for prototyping with a breadboard. However, Arduino also offers this board without headers pre-soldered.

Arduino Micro: direct access to on-board leds Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led – the green one on the left in the photo.

Behold the Rascal Micro. It’s running embedded Linux and has a dual-row of pin headers which probably seem pretty familiar. The idea here is to bring Arduino hardware (ie: shields) to a party… ...
