Product Description
The Motoron M1U550 Single I²C Motor Controller offers a compact solution for controlling one DC motor using a UART serial interface. Multiple Motoron controllers can be connected to the same serial bus, making it easy to expand a system with additional motors. The M1U550 operates from 1.8 V to 22 V and can deliver continuous output currents up to 1.8 A. This version ships with header pins included but not soldered in.
The Motoron M1T550 and M1U550 controllers make it easy to control a single bidirectional, brushed DC motor using an I²C or TTL serial (UART) interface, respectively. These compact (0.6? × 0.6?) boards operate from 1.8 V to 22 V and can deliver continuous output currents up to 1.8 A. 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:
- M1T550 (I²C):
- headers soldered
- headers included but not soldered in
- M1U550 (TTL serial):
- headers soldered
- headers included but not soldered in
The M1U550 has a TTL serial (UART) interface, and this version ships with a 1×12 breakaway male header included but not soldered in.
- One motor control channel allows for control of one bidirectional brushed DC motor per Motoron
- Wide operating voltage range: 1.8 V to 22 V (absolute maximum)
- Maximum output current per motor: 1.8 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:
- M1T550: I²C (up to 400 kHz)
- M1U550: 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 the motor 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
