About this product

An Arduino Uno-compatible all-in-one robot controller with an Atmega328, two motor-driver channels, sensor connections and sockets for optional wireless modules. The current gallery depicts V1.3 hardware. The wiki also covers older Atmega168/328 hardware and differs on the number of I2C connector sets; current and legacy claims are not treated as interchangeable. Cover image: Official DFR0004 gallery photograph of V1.3 hardware; legacy wiki claims are not confirmed for the pictured revision.
