A-Star 32U4 Robot Controller LV with Raspberry Pi Bridge (SMT Components Only)
This programmable module is designed to be the core of a small robot, either as an auxiliary controller atop a Raspberry Pi base or as a complete control solution on its own. Its ATmega32U4 AVR microcontroller comes preloaded with an Arduino-compatible bootloader. On-board hardware includes dual motor drivers that can deliver 1.8 A per channel and an efficient voltage regulator that allows the controller to work with a 2.7 V to 11 V input voltage, along with level shifters that enable it to interface with a Raspberry Pi. This version (item #3116) does not include any through-hole components or connectors, allowing for customized assembly or standalone use.
