12V 2.8A Dual H-Bridge, MD25


Designed to work with our EMG30 gear motors, the MD25 will drive two motors.
Controllled by Serial or the I2C Interface.
Two modes of operation, direct individual control of the motors or the ability to send a speed and a turn commands.

  • Voltage - 12v only. The 5v for the logic supplied from an on-board regulator, 300mA available for your own circuits.
  • Current - Up to 2.8A for each motor.
  • Encoder - Processes quadrature encoder inputs from motor. 360 counts per wheel turn when used with the EMG30.
  • Size - 71mm x 60mm
