A-Star 32U4 Robot Controller LV with Raspberry Pi Bridge
This programmable module combines with a Raspberry Pi to serve as the control center of a small robot or electronics project. Its ATmega32U4 AVR microcontroller comes preloaded with an Arduino-compatible bootloader, and the board includes dual motor drivers that can deliver 1.8 A per channel to two brushed DC motors. An efficient voltage regulator (2.7 V to 11 V input) and level shifters enable it to power and communicate with a Raspberry Pi. This version (item #3117) is assembled with selected through-hole connectors and components installed for use as a Raspberry Pi add-on.
