The Motoron M3T453 Triple I²C Motor Controller offers a compact solution for controlling three DC motors through an I²C interface. Multiple Motoron controllers can be connected to the same I²C bus, making it easy to expand a system with additional motors. The M3T453 supports motor supply voltages from 4.5 V to 44 V and can deliver continuous output currents up to 0.8 A per motor. This version has 0.1″-spaced pins for the logic and motor connections, and it ships without any headers included.

Available Options:

• with soldered headers(5084)
• without headers (5085)

The Motoron M3T453 controllers make it easy to control three bidirectional, brushed DC motors using an I²C interface. These compact boards support motor supply voltages from 4.5 V to 44 V and can deliver output currents up to 0.8 A continuous (2 A peak) per motor. 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.

Details for item #5084/5085

This version of the M3T453 has 0.1″-spaced pins for the logic and motor connections, and it ships with soldered headers.

The I²C connection to the Motoron can be made either through the board’s 0.1″-spaced pins or through its JST SH-style 4-pin connector, which works with our 4-pin JST SH-style cables and is compatible with SparkFun’s Qwiic and Adafruit’s STEMMA QT.

Features and specifications:

• Three motor control channels allow for independent control of up to three bidirectional brushed DC motors per Motoron
• Wide motor supply voltage range: 4.5 V to 44 V (absolute maximum)
• Maximum output current per motor: 0.8 A continuous, 2 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: I²C
• I²C clock speed: 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
• Current sensing (motor channels 1 and 2 only)
• Command timeout feature stops motors 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 (0.1″-pitch through-hole version only)
• Motoron Arduino library simplifies using the Motoron with an Arduino or compatible controller
• Motoron Python library simplifies using the Motoron with Python or MicroPython
• Comprehensive user’s guide
• Compact size:
• M3T453 with JST SH-style connectors: 0.85″ × 1.0″
• M3T453 with 0.1″-pitch through-holes: 0.7″ × 0.9″

The Motoron family

The tables below list the members of the Motoron family and show the key differences among them. Each type is available in several versions to provide different options for the through-hole connectors: they can be purchased as an assembled product with connectors soldered in, as a kit with connectors included but not soldered in, or (for Arduino and Raspberry Pi expansions) as a standalone board without connectors.

Package Includes:

• 1 x Motoron M3T453 Triple I²C Motor Controller with 0.1"-Pitch Through-Holes (No Headers)

                                                      OR

• 1 x Motoron M3T453 Triple I²C Motor Controller with Soldered Headers
