The Pololu Motoron M2T550 Dual I²C Motor Controller offers a compact solution for controlling two DC motors using an I²C interface.

Multiple Motoron controllers can be connected to the same I²C bus, making it easy to expand a system with additional motors. The M2T550 supports motor supply voltages from 1.8 V to 22 V and can deliver continuous output currents up to 1.6 A per motor.

Available with or without pre-soldered headers - select the required version before adding to your cart. The unsoldered version comes with a loose 16x1 header strip.


The Motoron M2T550 and M2U550 controllers make it easy to control two bidirectional, brushed DC motors using an I²C or TTL serial (UART) interface, respectively. These compact (0.6″ × 0.8″) boards support motor supply voltages from 1.8 V to 22 V and can deliver continuous output currents up to 1.6 A per motor. Multiple Motoron controllers can be configured to work on a single I²C or serial 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 or UART interface is needed regardless of how many Motorons you connect.

These Motoron controllers are available in several versions with different combinations of communication interfaces and connector options:

  • M2T550 (I²C) (this item):
    • headers soldered
    • headers included but not soldered in
  • M2U550 (TTL serial):
    • headers soldered
    • headers included but not soldered in

For smaller single-channel alternatives, consider the Motoron M1T550 and M1U550.

Connection Example

Features

  • Two motor control channels allow for independent control of up to two bidirectional brushed DC motors per Motoron
  • Wide motor supply voltage range: 1.8 V to 22 V (absolute maximum)
  • Maximum output current per motor: 1.6 A continuous, 5 A peak for <1 second
  • Reverse-voltage protection on motor power supply (down to −20 V)
  • Logic voltage range: 3.0 V to 4.9 V (5V nominal not recommended)
  • Control interface: M2T550: 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 using the Motoron with an Arduino or compatible controller
  • Motoron Python library simplifies using the Motoron with Python or MicroPython
  • Comprehensive user’s guide
  • Compact 0.6″ × 0.8″ size
