The Motoron M3S256 Triple Motor Controller Shield for Arduino makes it easy to control DC motors from an Arduino or Arduino-compatible board through an IC 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 M3S256 operates from 4.5 V to 48 V and can deliver continuous output currents up to 2 A per motor. This version ships with a variety of header pin and terminal block options included but not soldered in.

Three M3S256 versions are available to provide different options for the through-hole connectors:

Features and specifications:

• 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: IC
• IC 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 users guide
