Motoron M3S256 Triple Motor Controller Shield for Arduino

The Motoron M3S256 shield makes it easy to control up to three bidirectional, brushed DC motors with an Arduino or compatible board. It operates from 4.5 V to 48 V and can deliver continuous output currents up to 2 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 motor control channels allow for independent control of up to three bidirectional brushed DC motors per Motoron
* Wide operating voltage range: 4.5 V to 48 V
* Maximum output current per motor: 2.0 A continuous, 6.4 A peak for <1 second
* Reverse-voltage protection on motor power supply (down to -40 V)
* Logic voltage range: 2.8 V to 5.5 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 getting started using the Motoron with an Arduino or compatible controller
* Comprehensive user's guide
