EasyDriver Stepper Motor Driver

The EasyDriver Stepper Motor Driver is a simple, flexible, and beginner-friendly driver board for controlling bipolar stepper motors with precision. Based on the A3967 microstepping driver chip, it lets microcontrollers like Arduino, ESP32, ESP8266, and Raspberry Pi control stepper motors using just digital pulse and direction signals.

Designed for hobbyists and makers, EasyDriver takes care of the complex low-level motor control—handling current limiting, microstepping, and power drive—so you can focus on motion control in your project.

🔹 Key Features

1. Precision microstepping control with MS1 and MS2 pins (full, half, quarter, and eighth steps)
2. Works with 4-, 6-, or 8-wire bipolar stepper motors of any voltage
3. Adjustable current control (typically ~150 mA to ~750 mA per phase)
4. Motor supply voltage: ≈ 7 V to 30 V (higher voltages improve torque at high speeds)
5. Onboard voltage regulator for logic interface (configurable for 3.3 V or 5 V)
6. Broken-out Sleep and Enable pins for additional control

🔹 Applications

1. Precision motion control for 3D printers and CNC machines
2. Robotic arms and wheeled robots
3. Automated pan/tilt and positioning mechanisms
4. DIY and educational electronics kits
5. Arduino and microcontroller-based stepper motor projects
