DC 9-36V 12A PWM Motor Driver
The input voltage range of PWM motor driver controller is DC9-36V, rated current without heatsink is 12A, and rated current with simple cooling is 12-15A. Similar to L298 drive logic, three lines (PWM, IN1, IN2) control speed, clockwise rotation, counterclockwise rotation and braking.
Supports full PWM, clockwise or anticlockwise rotation can be controlled directly by the switch. The effective range of PWM is 0.1% to 100.0%. The motor speed controller can provide 5V power to the microcomputer or other controller, provide 5V output overcurrent protection and input signal overvoltage protection.
This PWM control module is designed for industrial use and is stable and reliable. It has anti-static circuit, transient suppression protection, undervoltage protection, interface ESD and overvoltage protection.
Control Signal Logic
Note: 0 low, 1 high, "×" any level, variable low.
- COM - Ground, 5VO - 5V Output, for providing 5V power supply of microcontroller and other controllers.
- PWM pin external PWM, if key control is used, PWM pin should be connected with 5VO;
- IN1 and IN2 for two motor positive and negative rotation, brake control signal.

Usage
1. Use microcontroller to control motor rotation wiring method
PWM pin to PWM output of microcontroller
IN1, IN2 and two IOs of microcontroller to control
5VO can provide 5V power supply for microcontroller
Use only pushbutton to control motor by reversing wiring method
PB1 and PB2 are two switches. When PB1 is pressed and PB2 is not pressed, IN1 is high, IN2 is low, the motor runs
When PB2 is pressed and PB1 is not pressed, IN1 is low, IN2 is high, Motor runs reverse
PB1 and PB2 pressed, IN1 and IN2 low, motor brake
Use PWM generator in motor speed control wiring method
PWM generator adjustable by switch, choose frequency and duty cycle to control motor speed.
For two switches PB1 and PB2 control the rotation direction of the motor, when PB1 and PB2 are pressed the motor brakes.
