The Motoron M2U550 Dual I²C Motor Controller offers a compact solution for controlling two DC motors using a UART interface. Multiple Motoron controllers can be connected to the same serial bus, making it easy to expand a system with additional motors. The M2U550 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 M2U550 has a non-inverted TTL serial (UART) interface, and this version ships with a 1×16 breakaway male header included but not soldered in.

Two motor control channels allow for independent control of up to two bidirectional brushed DC motors per Motoron
Wide operating voltage range: 1.8 V to 22 V (absolute maximum)
Maximum output current per motor: 1.6 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 5.0 V
Control interface:
- M2T550: I²C (up to 400 kHz)
- M2U550: non-inverted TTL serial (up to 250 kbps)
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
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
Motoron Arduino library simplifies using the Motoron with an Arduino or compatible controller
Motoron Python library simplifies using the Motoron with Python or MicroPython
