Quad Stepper Motor Controller Board for Raspberry Pi

This neat Quad Stepper Motor Controller Board plugs directly onto the 40-pin GPIO header of your Raspberry Pi, instantly adding the capability to drive up to four small stepper motors simultaneously. It is designed in the Raspberry Pi Zero form factor, making it a compact and perfect companion for all versions of the Raspberry Pi that feature a 40-pin GPIO connector, from the Pi Zero to the latest models.

Power and Compatibility

The board offers flexible power options to suit your project's needs. You can power it via the Raspberry Pi's own 5V rail using a convenient 2-pin terminal block, which allows you to supply the exact voltage required by your motors. Alternatively, a Micro USB port provides a dedicated 5V-only input for the controller board itself, ensuring clean and stable operation.

Clear Pinouts and Visual Feedback

Each of the four motor channels is clearly mapped to specific physical and GPIO pins on the Raspberry Pi header, eliminating guesswork during setup. For Motor A, use physical pins 11, 12, 13, and 15 (GPIO 17, 18, 27, 22). Motor B connects to pins 16, 18, 22, and 7 (GPIO 23, 24, 25, 04). Motor C uses pins 33, 32, 31, and 29 (GPIO 13, 12, 6, 5). Finally, Motor D is connected via pins 38, 37, 36, and 35 (GPIO 20, 26, 16, 19). A highly useful feature is the set of white LEDs associated with each control pin, providing clear visual feedback of the stepper signals as they are sent, which is invaluable for debugging and understanding motor behaviour.

Easy Setup and Use

Fully assembled and ready to use straight from the packet, this controller requires no soldering. Simply connect it to your Raspberry Pi, attach your stepper motors to the four provided connectors, and apply power. Its compact dimensions (36.5mm x 26mm x 13.5mm) and lightweight design (15 grams) make it ideal for embedded projects, robotics, CNC prototypes, automated camera sliders, or any application where
