Overview

This 2-Channel Motor Drive Module (AT8236/TB6612FNG) is designed to drive two DC motors (including geared motors and encoder motors). The AT8236-based module supports driving 2-channel motors with Hall encoder at the same time, supports 5-12V power input, and includes input anti-reverse connection protection. It also integrates a voltage regulator for external power output (5V/3A or 3.3V/500mA) and an on-board VM voltage detection circuit for real-time supply voltage reading. Multiple modules can be powered in cascade to build 2WD/4WD/MWD smart car projects.
