Motoron M1T550 - I2C motor driver for 1 motor, 1.8A, 1.8-22V

I2C motor controler for 1 DC motor - Motoron

The Motoron M1T550 controllers make it easy to control a single bidirectional, brushed DC motor using an I²C interface (see the M1U550 for TTL serial/UART version).

This compact board (15mm x 15m size) can drive a motor from 1.8 V to 22 V with a maximum continuous current of 1.8 A. Multiple Motoron controllers can be configured to work on a single I²C allowing independent control of several motors.

Most common motor driver as L298 or L293 do needs several digital pins + PWM pin to control a single moteur.
The Motoron board only need a single I2C bus (2 wires) shared among the various sensors and Motoron board. Several Motoron can be connected to a single bus.

Technical details

• One motor control channel allows for control of one bidirectional brushed DC motor per Motoron
• Wide motor supply voltage range: 1.8 V to 22 V (absolute maximum)
• Maximum output current per motor: 1.8 A continuous, 5 A peak for <1 second
• Reverse-voltage protection on motor power supply (down to −20 V)
• Logic voltage range: 3.0 V to 4.9 V (5V nominal not recommended)
• Control interface: 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 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 or MicroPython
