Modules for DIY Robotics, Automation and Embedded Projects 

The BMD25/45 is a 7–45V, 25A bidirectional brushed DC motor driver for robotics, automation, and embedded motion-control projects. It provides PWM speed control, EN/DIR control inputs, built-in protection, and a 5V output for an external controller. 

Specifications

• Dimensions: 60 x 100mm

• Operating Voltage: DC 7V to 45V

• Maximum Motor Current: 25A, with hardware current limiting even when using static EN/DIR inputs. 

• 5V output for external controller, 500mA max

• EN/DIR Inputs compatible with 1.8V, 3.3V, 5V

• PWM frequency up to 22kHz
  
  Features

• Bidirectional control

• EN/DIR buttons to test the connected motor without an external controller.

• Undervoltage, overcurrent, and driver over-temperature protection

• Power switches over-temperature protection

• LED indicators for PCB over-temperature, driver fault, and 25A current limiting.
