The AAduino is an wireless Arduino clone the size of an AA battery with Keystone battery terminals rotated 180° to act as positive and negative terminals. It is meant to go inside a 3xAA battery holder creating a very small wireless node. Powered by an ATMega328p, it is fitted with an RFM69CW companion, two DS18B20 temperature sensors and an indicator LED
