Elecrow Stepper Motor HAT for Raspberry Pi - Dual A4988 Driver | Compoden
Elecrow Stepper Motor HAT for Raspberry Pi
The Elecrow Stepper Motor HAT mounts directly onto a Raspberry Pi’s 40‑pin GPIO header to add two A4988 stepper motor drivers. It lets you run two bipolar stepper motors independently for precision motion control in robotics, CNC machines, or automated camera rigs. On‑board current‑adjustment potentiometers and five microstep modes give you full control over torque and positioning.

Compatibility
The HAT fits any Raspberry Pi with a 40‑pin GPIO header: Pi 4, Pi 3, Pi 2, Pi Zero (with header), and Pi 5. It works with all bipolar stepper motors rated up to 2 A per coil and 8 V–35 V. Common pairings include NEMA 17 motors and 12 V or 24 V power supplies.
Wiring Notes
Plug the HAT directly onto the Raspberry Pi’s GPIO pins. Connect your motor power supply to the screw‑terminal block (8 V–35 V, center‑positive) and attach stepper motors to the M1 and M2 terminals. Before running, set the drive current by measuring the reference voltage on each potentiometer; the A4988’s step, direction, and enable pins map to standard GPIO lines.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Raspberry Pi 5?
Yes. The HAT stacks onto the 40‑pin GPIO header of the Pi 5. You may need to install libraries such as RPi.GPIO or pigpio, which are fully supported on the Pi 5.
What type of stepper motors can I use?
Any bipolar stepper motor with a coil current rating up to 2 A and an operating voltage between 8 V and 35 V. NEMA 17 motors are a common choice.
Does the board need an external power supply?
Yes, a separate DC power source (8 V–35 V) must be connected to the screw terminals for the motors. The Raspberry Pi’s 5 V rail cannot supply the required motor current.
