Description
Product information "Pololu A-Star 32U4 robot controller with Raspberry Pi Bridge (SMT components only)"
This programmable module is designed as the centrepiece of a small robot, either as an additional controller on a Raspberry Pi base or as a complete control solution on its own. The ATmega32U4 AVR microcontroller is pre-installed with an Arduino-compatible bootloader. The on-board hardware includes two motor drivers capable of delivering 1.8 A per channel and an efficient voltage regulator that allows the controller to operate with a 2.7 V to 11 V input voltage, along with level shifters that allow it to interface with a Raspberry Pi. This version (item #3116) contains no through-hole components or connectors, allowing custom assembly or standalone use.

Safety instructions
- Before use, ensure that the voltage and current are compatible with the Raspberry Pi and the connected motors.
- Do not connect any components while the Raspberry Pi is energised.
- Connect GPIO pins carefully to avoid short circuits or damage to the hardware.
- Never connect the GPIO pins directly to power sources such as batteries without suitable resistors or protective circuitry.
- Protect the device from moisture, extreme temperatures and direct sunlight.
- Mount all screws and mechanical components securely and firmly to prevent loosening due to vibrations.
- Be aware of heat build-up during prolonged operation; ensure sufficient cooling if necessary.
- Dispose of in accordance with local regulations for electronic waste.
- Remove batteries or other energy sources from the device before disposal.
- Do not reuse any mechanically defective or damaged parts.
- If you are unsure about the use or installation of the device, read the manufacturer's technical documentation and safety instructions.
- Only allow children to use the appliance under adult supervision.
