The Motoron M1T550 and M1U550 controllers make it easy to control a single bidirectional, brushed DC motor using an I²C or TTL serial (UART) interface, respectively. These compact (0.6" × 0.6") boards operate from 1.8 V to 22 V and can deliver continuous output currents up to 1.8 A. Multiple Motoron controllers can be configured to work on a single I²C or serial bus, allowing independent control of many motors. Unlike most of Pololu's 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 dual-channel alternatives, consider the Motoron M2T550 and M2U550.

Features and specifications

  • One motor control channel allows for control of one bidirectional brushed DC motor per Motoron
  • Wide operating voltage range: 1.8 V to 22 V (absolute maximum)
  • Maximum output current per motor: 1.8 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 5.5 V
  • Control interface:
    • M1T550: I²C (up to 400 kHz)
    • M1U550: non-inverted TTL serial (up to 250 kbps)
  • 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 the motor 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" × 0.6" size

The Motoron family

The tables below list the members of the Motoron family and show the key differences among them. Each type is available in several versions to provide different options for the through-hole connectors: they can be purchased as an assembled product with connectors soldered in, as a kit with connectors included but not soldered in, or (for Arduino and Raspberry Pi expansions) as a standalone board without connectors.
