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
  • Size: 15 × 15mm
