The A-STAR 32U4 ROBOT CONTROLLER SV (Part #2819) is a motor controller and Arduino-compatible microcontroller board from Pololu. This versatile board can be used to control a variety of small robots or other projects. It features an ATmega32U4 microcontroller with 32 KB of program space and 2.5 KB of RAM, as well as USB and serial access. Additionally, the board provides three Analog/Digital (A/D) and seven Digital/Analog (D/A) ports, giving you plenty of control options to use with your projects. The A-STAR 32U4 ROBOT CONTROLLER SV is four-layer, with two of the layers dedicated to the power distribution network, allowing for more reliable current distribution and efficient dissipation of heat. Additionally, the board is equipped with an array of components which make it suitable for motor control applications, such as a dual H-bridge motor driver and additional onboard MOSFET for controlling up to four DC motor outputs, as well as two encoders for feedback from the motors. This board is a great option for controlling small or medium robotics projects.
