Pololu Motoron M2T550 Dual IC Motor Controller

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

Multiple Motoron controllers can be connected to the same IC 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 16×1 header strip.

The Motoron M2T550 and M2U550 controllers make it easy to control two bidirectional, brushed DC motors using an IC 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 IC 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 IC 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 (IC) (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.
