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 * Reverse-voltage protection on motor power supply (down to -40 V) * Logic voltage range: 3.0 V to 5.5 V * Control interface: M1T256: I²C (up to 400 kHz) * Optional cyclic redundancy checking (CRC) * Configurable motion parameters: * Max acceleration/deceleration forward/reverse * Starting speed forward/reverse * Direction change delay forward/reverse * PWM frequency: eight options available from 1 kHz to 80 kHz * Command timeout feature stops the motor if the Motoron stops receiving commands * Configurable automatic error response * Motor power supply (VIN) voltage measurement * Two status LEDs * Motor direction indicator LEDs * Error output for easier detection of error conditions * Motoron Arduino library simplifies using the Motoron with an Arduino or compatible controller * Motoron Python library simplifies using the Motoron with Python code * Comprehensive user’s guide * Compact 0.6″ × 0.6″ size Specifications Channels 1 Model Motoron M1T256 Control interface I²C Minimum operating voltage 4.5 V Maximum operating voltage 48 V Continuous output current per channel 2.2 A Peak output current per channel 6.4 A Reverse voltage protection?
