Description
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
