The Motoron M2T256 controller makes it easy to control two bidirectional, brushed DC motors using an I²C interface.

These compact (0.6″ × 0.8″) boards operate from 4.5 V to 48 V and can deliver continuous output currents up to 1.8 A per motor. Multiple Motoron controllers can be configured to work on a single I²C bus, allowing independent control of many motors.

Unlike most of our motor drivers, the Motoron does not require any PWM outputs or timers on your microcontroller. Instead, only a single I²C interface is needed regardless of how many Motorons you connect.

The M2T256 has an I²C interface, and this version ships with soldered headers. We also stock a single-channel version.

Example Circuit


  • Two motor control channels allow for independent control of up to two bidirectional brushed DC motors per Motoron
  • Wide operating voltage range: 4.5 V to 48 V (absolute maximum)
  • Recommended maximum nominal battery voltage is approximately 36 V
  • Maximum output current per motor: 1.8 A continuous, 6.4 A peak for <1 second
  • Reverse-voltage protection on motor power supply (down to -40 V)
  • Logic voltage range: 3.0 V to 5.5 V
  • Control interface: I²C (up to 400 kHz)
  • Optional cyclic redundancy checking (CRC)
  • Configurable motion parameters:
  • Max acceleration/deceleration forward/reverse
  • Starting speed forward/reverse
  • Direction change delay forward/reverse
  • PWM frequency: eight options available from 1 kHz to 80 kHz
  • Command timeout feature stops motors if the Motoron stops receiving commands
  • Configurable automatic error response
  • Motor power supply (VIN) voltage measurement
  • Two status LEDs
  • Motor direction indicator LEDs
  • Error output for easier detection of error conditions
  • Motoron Arduino library simplifies getting started using the Motoron with an Arduino or compatible controller
  • Comprehensive user’s guide
  • Compact 0.6″ × 0.8″ size
