MOTORPLATE

The Pi-Plates MOTORplate brings a rich set 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. They can also be stacked eight high and are compatible with all other Pi-Plates boards. 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.

• 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:
• The Raspberry Pi 5VDC supply
• A dedicated power input (15V MAX)
• Dedicated onboard processor
• Calculates and provides real time acceleration trajectories
• Allows for future code updates
• Only needs two dedicated RPI pins (GPIO 25 and CE1)1
• All features accessible via rich Python command set
• 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
• Conforms to ROHS, FCC Part 15 Class A, and CE standards
• 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
• Dimensions: 100mm long x 75mm wide X 15mm high
