This programmable module combines with a Raspberry Pi to serve as the control center of a small robot or electronics project. Its Atmel ATmega32U4 microcontroller comes preloaded with an Arduino-compatible bootloader, and the board includes dual motor drivers that can deliver 1.7 A per channel to two brushed DC motors. An efficient voltage regulator (5.5 V to 36 V input) and level shifters enable it to power and communicate with a Raspberry Pi. This version (item #3119) is assembled with selected through-hole connectors and components installed for use as a Raspberry Pi add-on.
