A-Star 32U4 Robot Controller SV 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 1.7 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.

Notes:
- 1
- Without included mounting hardware.
- 2
- Note that 4 KB of the MCU's 32 KB of flash memory is used by the pre-installed USB bootloader. All 32 KB is available when programming via the ISP header rather than the bootloader.
- 3
- Some I/O lines are used by on-board hardware.
- 4
- Available current depends on input voltage, current consumed by the board, ambient conditions, and regulator topology. See product documentation and performance graphs for details.
