DEV-14149 Datasheet PDF - SparkFun Electronics

Description:
   The MOTORplate from Pi-Plates brings a suite of professional motion control features to your Raspberry Pi. These plates can each control a combination of two stepper motors, four DC motors or one stepper and two DC motors. An onboard microprocessor does all the hard work including controlling acceleration trajectories and microstepping. By offloading these functions, your Raspberry Pi is free to perform other tasks. Use this board to control a precision XY stage driven by stepper motors. Or, drive the treads of your killer robot.

FEATUREs:
• Can drive 2 stepper motors or 4 DC motors or a combination of the two
• Output currents as high as 1.2 amps (avg) and 3.2 amps (peak)
• Motor driving MOS transistors ensure cool and efficient operation
• Auxiliary power inputs with selectors and reverse-voltage protection allow each motor controller
   chip to be powered by either the:
   o The Raspberry Pi 5VDC supply
   o Dedicated power input (15V MAX)
• Dedicated onboard processor
• Calculates and provides real-time acceleration trajectories
• Only needs two dedicated RPI pins (GPIO 25 and CE1)
• Compatible with all versions of Raspberry Pi
• Design allows up to eight MOTORplate boards to be stacked together for eight times the drive
   capability: 16 stepper motors or 32 DC motors!
• Uses less than 10mA of DC current during standby2
• All inputs ESD and overvoltage protected
• +5 and ground available on terminal blocks for powering hall effect sensors, optoisolators and limit switches
• Includes programmable LED
• Compatible with ServoBlaster
