The Motoron M2T256 Dual I²C Motor Controller offers a compact solution for controlling two DC motors using 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 M2T256 operates from 4.5 V to 48 V and can deliver continuous output currents up to 1.8 A per motor.

Available Options:

This version ships with header pins included but not soldered in.
This version ships with soldered headers.

Overview:

The Motoron M2T256 and M2U256 controllers make it easy to control two bidirectional, brushed DC motors using an I²C or TTL serial (UART) interface, respectively. These compact (0.6″ × 0.8″) boards operate from 4.5 V to 48 V and can deliver continuous output currents up to 1.8 A per motor. Multiple Motoron controllers can be configured to work on a single I²C or serial 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 or UART interface is needed regardless of how many Motorons you connect.

These Motoron controllers are available in several versions with different combinations of communication interfaces and connector Options:

M2T256 (I²C):

headers soldered
headers included but not soldered in

For smaller single-channel alternatives, consider the Motoron M1T256 and M1U256.

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.
