Dual Stepper Motor Driver Arduino Shield

The Dual Stepper Motor Driver Arduino Shield is an advanced motor control expansion board designed to simplify the operation of two independent bipolar stepper motors using Arduino and compatible development boards. The shield is built around two reliable A3967 microstepping motor driver chips, the same drivers used in the popular EasyDriver modules.

The shield supports stepper motors operating from 4.75V to 30V DC with output currents up to 750mA, making it suitable for a wide range of robotics, automation, and precision motion applications. It supports multiple stepping resolutions including full-step, half-step, quarter-step, and eighth-step modes, allowing smoother and more accurate motor movement.

The A3967 drivers include important protection and performance features such as automatic current decay mode selection, crossover-current protection, and thermal shutdown circuitry for safe and stable operation.

In addition to motor control, the shield provides convenient 3-pin analog headers, along with I2C and serial communication ports for connecting sensors, modules, and external devices. This makes the shield highly suitable for robotics projects, CNC systems, 2D plotters, and educational motion-control applications.
