4tronix Quad Stepper Motor Controller Board for Raspberry Pi
4tronix quad stepper motor controller board for Raspberry Pi, driving up to four stepper motors via the 40-pin GPIO header. Fully assembled.
The 4tronix Quad Stepper Motor Controller Board drives up to four small stepper motors simultaneously and plugs directly onto the 40-pin GPIO header of a Raspberry Pi. Its Raspberry Pi Zero form factor keeps the board compact.
Overview
This controller adds the ability to drive up to four small stepper motors to any Raspberry Pi that features a 40-pin GPIO connector, from the Pi Zero to the latest models. The board is fully assembled and ready to use straight from the packet, so no soldering is required. Its compact dimensions of 36.5 mm x 26 mm x 13.5 mm and weight of 15 g make it suitable for space-constrained builds.
Power and Compatibility
The board offers flexible power options:
- Power via the Raspberry Pi 5V rail using a 2-pin terminal block, allowing the exact voltage required by your motors to be supplied
- A Micro USB port providing a dedicated 5V-only input for the controller board itself
Clear Pinouts and Visual Feedback
Each of the four motor channels is mapped to specific physical and GPIO pins on the Raspberry Pi header:
- Motor A: physical pins 11, 12, 13 and 15 (GPIO 17, 18, 27, 22)
- Motor B: physical pins 16, 18, 22 and 7 (GPIO 23, 24, 25, 04)
- Motor C: physical pins 33, 32, 31 and 29 (GPIO 13, 12, 6, 5)
- Motor D: physical pins 38, 37, 36 and 35 (GPIO 20, 26, 16, 19)
A white LED is associated with each control pin, providing visual feedback of the stepper signals as they are sent. This is useful for debugging and understanding motor behaviour.
Easy Setup and Use
Connect the board to your Raspberry Pi, attach your stepper motors to the four provided connectors, and apply power. The board is suitable for embedded projects, robotics, CNC prototypes and automated camera sliders.
