Motoron M3S550 Triple Motor Controller Shield for Arduino (No Connectors)
All prices are VAT included
The Motoron M3S550 Triple Motor Controller Shield for Arduino makes it easy to control DC motors from an Arduino or Arduino-compatible board through an I²C interface. Each module can independently control up to three motors, and multiple shields can be stacked on top of the same Arduino for projects that need to control even more motors. The M3S550 supports motor supply voltages from 1.8 V to 22 V and can deliver continuous output currents up to 1.7 A per motor . This version is just the motor controller by itself , without any header pins or terminal blocks included.
Overview
The Motoron M3S550 shield makes it easy to control up to three bidirectional, brushed DC motors with an Arduino or compatible board, such as the A-Star 32U4 Prime . It supports motor supply voltages from 1.8 V to 22 V and can deliver continuous output currents up to 1.7 A per motor. Multiple Motoron controllers can be stacked on top of each other, allowing independent control of many motors. Unlike most of our motor drivers and motor driver shields , the Motoron does not require any PWM outputs or timers on your Arduino. Instead, the Arduino communicates with the Motoron using I²C, so only two I/O lines are needed regardless of how many Motorons you connect.

Three M3S550 versions are available to provide different options for the through-hole connectors:
- Motoron M3S550 with soldered stackable headers and terminal blocks
- Motoron M3S550 with headers and terminal blocks included but not soldered in
- Motoron M3S550 without any headers or terminal blocks included
For applications using a Raspberry Pi, consider the Motoron M3H550 instead (also available with different connector options).

Motoron M3S550 Triple Motor Controller Shield for Arduino (No Connectors). |
|---|
This version of the Motoron M3S550 is just the assembled PCB module as shown above, with no connectors included. This version is intended for those who want to solder wires directly to the board or use different connectors from those included with other versions. We have a variety of connectors available separately.

Features and specifications
- Three motor control channels allow for independent control of up to three bidirectional brushed DC motors for Motoron
- Wide motor supply voltage range: 1.8 V to 22 V (absolute maximum)
- Maximum output current per motor: 1.7 A continuous, 5 A peak for <1 second
- Reverse-voltage protection on motor power supply (down to −20 V)
- Logic voltage input (IOREF) range: 3.1 V to 5.5 V
- Logic voltage: 3.3 V typical, but lower if IOREF is less than 3.3 V (produced by an LDO powered from IOREF)
- Compatible with 3.3 V and 5 V I²C buses (maximum signal voltage is 6.5 V)
- Control interface: I²C
- I²C clock speed: up to 400 kHz
- 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 Arduino stops functioning
- Configurable automatic error response
- Motor power supply (VIN) voltage measurement
- Optional pins make it easy to power the Arduino from reverse-protected motor power, either directly or through an external regulator (not included)
- Two status LEDs
- Motor direction indicator LEDs
- Motoron Arduino library simplifies using the Motoron with an Arduino or compatible controller
- Comprehensive user's guide
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.
