Model D157B is an AT8236 dual‑channel DC motor driver module with built‑in voltage regulator, designed for smart car and robot projects. Powered by the AT8236 chip, it drives two DC motors simultaneously with forward/reverse rotation and stepless speed regulation, delivering higher drive current than TB6612. Built‑in 3.3V & 5V regulated outputs supply power for main controllers and sensors. It features short‑circuit, over‑temperature and over‑current protection, plus an encoder sampling interface. Accepts 5.5‑17V motor power input with 0‑100KHz PWM control. Compatible with TT motor, MG310, MG540 and other common motors, it is a reliable motor‑drive solution for robot car development.
