The Motoron M1T256 Single I²C Motor Controller offers a compact solution for controlling one DC motor 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 M1T256 supports motor supply voltages from 4.5 V to 48 V and can deliver continuous output currents up to 2.2 A.

The Motoron M1T256 and M1U256 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 4.5 V to 48 V and can deliver continuous output currents up to 2.2 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:

M1T256 (I²C)(Available Options):

• headers soldered
• headers included but not soldered in
