This is an H-bridge driver module that enables any ECU to drive a DC motor using a single PWM output and a single non-PWM output for direction.

Compatible with all of our electronic control units.

Available in a dual channel option to drive two electric motors from a single box.


  • Operating frequency range 100-5000Hz
  • Operating voltage range 8-19V, reverse polarity protected
  • Operating temperature range -40 to 85°C
  • Current rating 25A peak (1 second), 8A continuous
  • Maximum duty cycle 90% (automatically shuts off if exceeded)
  • Dimensions (l/b/h) 90x60x31mm


  1. Forward positive output (reverse negative)
  2. Reverse positive output
  3. Ground
  4. Ground
  5. Direction input (reverse if grounded, forward otherwise)
  6. PWM input (active low)
  7. +12V input
  8. +12V input
If current is expected to stay below 8A at all times a single ground and single +12 feed are sufficient. For best performance at higher currents doubling the wires is recommended.

Comes with matching connectors and crimp terminals.
