Motoron M2T256 Dual I²C Motor Controller (Pins Pre-soldered)
The Motoron M2T256 controller makes it easy to control two bidirectional, brushed DC motors using an I²C interface.
These compact (0.6″ × 0.8″) boards operate 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 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 interface is needed regardless of how many Motorons you connect.
The M2T256 has an I²C interface, and this version ships with soldered headers. We also stock a single-channel version.
Example Circuit
Features
- Two motor control channels allow for independent control of up to two bidirectional brushed DC motors per Motoron
- Wide operating 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 <1 second
