Arduino recently updated their small form-factor Arduino Mini and it’s now shipping from the Maker Shed. The Arduino Mini R05 is based on the same ATmega 328 processor as the Arduino Uno, but measures a scant 1.25″x0.73″ making it perfect for breadboards and embedded applications. The R05 update includes a new, smaller chip package and a revised PCB making it possible to fit all the components on the top of the board. It also features a reset button which was lacking in previous versions. Like the earlier models, the Mini R05 requires the use of an FTDI breakout such as the FTDI Friend for programming.
