Motoron M1U550 Single Serial Motor Controller (Header Pins Soldered)

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 support motor supply voltages 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 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:

• M1T550 (I²C):
  • headers soldered
  • headers included but not soldered in
• M1U550 (TTL serial):
  • headers soldered
  • headers included but not soldered in

For dual-channel alternatives, consider the Motoron M2T550 and M2U550.

The M1U550 has a TTL serial (UART) interface, and this version ships with soldered headers.

• One motor control channel allows for control of one bidirectional brushed DC motor per Motoron
• Wide motor supply voltage range: 1.8 V to 22 V (absolute maximum)
• Maximum output current per motor: 1.8 A continuous, 5 A peak for
