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.

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.

Four M3T453 versions are available to provide different connector options:

M3T453 with JST SH-style connectors(Options available):

• with VIN terminal block
• without VIN connector

Details for item #5083

The I²C connection to the Motoron can be made through either of the board’s two 4-pin connectors, which work with our 4-pin JST SH-style cables and are compatible with SparkFun’s Qwiic and Adafruit’s STEMMA QT (the second connector can be used to chain additional Motorons or other I²C devices). The motor connectors are compatible with our 2-pin JST SH-style cables and JST SH-Style Connector Board for Micro Metal Gearmotors.
