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.
Pi-Plates are a family of stackable and interchangeable add-on circuit boards that allow you to interact with the outside world using your Raspberry Pi. Every Pi-Plate is designed to provide a robust set of features at minimal cost while using the fewest pins possible on the RPi header. Pi-Plates are mechanically and electrically compatible with all revisions of the Raspberry Pi with 40 pin headers (including the Pi 3 Model B and Pi Zero) and are designed to satisfy the needs of hobbyists, experimenters and professionals.
