The EasyDriver is a simple stepper motor driver board based on the Allegro A3967 IC. It accepts a digital step/direction input (3.3 V or 5 V logic) and drives bi-polar stepper motors (4, 6, or 8 wire) at any voltage within the 7–30 V supply range.
The board features adjustable current control from 150 mA to 750 mA per phase, selectable microstepping resolution (full, half, quarter, and eighth steps), and an on-board voltage regulator configurable for 5 V or 3.3 V digital logic.
Key Features
- A3967 Stepper Driver – Simple step/direction interface
- Wide Motor Compatibility – Drives 4, 6, or 8 wire bi-polar stepper motors at any voltage
- Adjustable Current – 150–750 mA per phase
- Microstepping – Full, half, quarter, and eighth step resolution (defaults to eighth)
- 7–30 V Supply – Higher voltage enables higher torque at speed
- 3.3 V / 5 V Logic – Selectable via solder jumper SJ2
- Sleep & Enable Pins – Broken out for additional control

Jargon buster
Plain-language definitions for the technical terms used above.
- motor driver
- An electronic circuit that lets a low-power controller switch and control a motor that needs more current than the controller pins can safely provide. Checking motor driver support matters because pumps and motors usually cannot be connected directly to a microcontroller output.
- solder jumper
- A solder jumper is a small pair or group of pads on a circuit board that can be bridged or cut with solder to change a hardware setting. It matters because changing modes may require careful soldering rather than just changing software.
- Torque
- A twisting force that causes something to rotate, usually measured in newton-metres or kilogram-centimetres. It matters when choosing motors, servos, gears, and tools because higher torque is needed to lift heavier loads, turn larger wheels, or move mechanisms without stalling.
