Motoron M2U256 Dual Serial Motor Controller (Header Pins Soldered)

The Motoron M2T256 and M2U256 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 4.5 V to 48 V and can deliver continuous output currents up to 1.8 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:

• M2T256 (I²C):
  • headers soldered
  • headers included but not soldered in
• M2U256 (TTL serial):
  • headers soldered
  • headers included but not soldered in

For smaller single-channel alternatives, consider the Motoron M1T256 and M1U256.

The M2U256 has a non-inverted TTL serial (UART) interface, and this version ships with soldered headers.

• Two motor control channels allow for independent control of up to two bidirectional brushed DC motors per Motoron
• Wide motor supply voltage range: 4.5 V to 48 V (absolute maximum)
  • Recommended maximum nominal battery voltage is approximately 36 V
• Maximum output current per motor: 1.8 A continuous, 6.4 A peak for
