DIYables BTS7960 43A Motor Driver Module H Bridge PWM for Arduino Smart Car
Click to zoom
Quick Overview
This DIYables BTS7960 motor driver module uses dual BTS7960 half bridge chips to form a full H bridge capable of driving brushed DC motors at up to 43A. It runs from a 5.5V to 27V motor supply, making it a good fit for high power gear motors, robot drivetrains, and smart car chassis that a small L298N style driver cannot handle.
The driver stage is isolated from your microcontroller by an on-board isolation chip, so a fault on the motor side does not reach the MCU. Only four lines are needed between the controller and the module: GND, 5V, PWM1, and PWM2. The isolation chip can share the 5V supply with your MCU or use the module's on-board 5V. Two PWM inputs accept frequencies up to 25kHz for smooth speed control and forward or reverse direction, with built-in current limiting, two error signal outputs for fault feedback, an on-board 5V power indicator, and voltage indication on the motor output end. A solderable heat sink area lets you add cooling for sustained high current loads.
This listing includes 3 BTS7960 motor driver modules, ideal for smart car and robot chassis, conveyor and winch drives, electric scooter and wheelchair motors, and other Arduino, ESP32, and Raspberry Pi motor control projects.
Key Features
