Motoron M3S256 Triple Motor Controller Shield (No Connectors)

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 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 M3S256 operates from 4.5 V to 48 V and can deliver continuous output currents up to 2 A per motor. This version ships without any header pins or terminal blocks included.

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

• Motoron M3S256 with soldered stackable headers and terminal blocks
• Motoron M3S256 with headers and terminal blocks included but not soldered in
• Motoron M3S256 without any headers or terminal blocks included

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: 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
