Product Info

This low-cost dual DC motor driver module is perfect for implementing robotic or mechatronic applications with MicroCore-11 or any microcontroller of your choice. The 2-inch (50.8mm) square form-factor board matches the MicroCore-11 family, and has mounting holes in all four corners for stacking or mounting to a substrate. Each of the two H-bridge circuits controls one motor, at up to 1 Amp of drive capability. Separate Enable and Direction pin for each channel makes controlling it from any microcontroller a very simple task. Simply apply a PWM waveform to the Enable pin and vary the duty cycle to adjust the motor speed. A logic level signal applied to the Direction pin will control the direction of rotation of the motor.

A 500mA regulator provides ample current at 5V for powering your microcontroller board and other sensors and actuators you may wish to use (e.g. Sharp IR distance sensor, sonar range finder, hobby servo motor, etc.)

• 2" x 2" standard MicroCore-11 form factor
• based on SN754410NE dual H-bridge chip from TI
• 1 Amp per channel, nominal
• drives two DC motors or one stepper motor
• cascadable-- add a second board for two more drivers
• or wire two channels in parallel for double the drive current
• use two PWM signals to control speed (PWM) and two port pins to control direction of current through each H-bridge
• jumperable port pin assignments
• LED motor direction indicators
• separate connector for motor supply voltage (up to 24V)
• on-board 5V 500 mA regulator can power all logic and any attached MCU boards and sensors
• grid of plated-through holes on 0.1" centers for adding sensors, etc.
• power and motor connections via 2-pin Molex connectors
• mating power and motor connector housings and crimp terminals are supplied
• dual 26-pin bussed connector patterns for easy stacking
• several connector options offer many configuration possibilities
• use with prototyping board and backplanes, or stack with other boards. Click here for examples.
