Product Description
The Motoron M2T550 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 M2T550 operates from 1.8 V to 22 V and can deliver continuous output currents up to 1.6 A per motor. This version ships with header pins included but not soldered in.
The Motoron M2T550 and M2U550 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 1.8 V to 22 V and can deliver continuous output currents up to 1.6 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:
- M2T550 (I²C):
- headers soldered
- headers included but not soldered in
- M2U550 (TTL serial):
- headers soldered
- headers included but not soldered in
For smaller single-channel alternatives, consider the Motoron M1T550 and M1U550.
The M2T550 has an I²C interface, and this version ships with a 1×16 breakaway male header included but not soldered in.
