The 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 operates from 1.8 V to 22 V and can deliver continuous output currents up to 1.6 A per motor.

Options Available:

  • This version ships with header pins included but not soldered in.
  •  This version ships with soldered headers.

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 operate 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:

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