Motoron M1T256 Single I²C Motor Controller (Pins Pre-soldered)

The Motoron M1T256 controller makes it easy to control a single bidirectional, brushed DC motors using an I²C interface.

These compact (0.6″ × 0.6″) boards operate from 4.5V to 48V and can deliver continuous output currents up to 2.2A. 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 M1T256 has an I²C interface, and this version ships with soldered headers. We also stock a dual-channel version.

Example Circuit

Features

• One motor control channel allows for control of one bidirectional brushed DC motor 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: 2.2 A continuous, 6.4 A peak for <1 second
