L9110S H Bridge Stepper Motor Dual DC Driver Controller Module For Arduino

This product is not available in your location yet

Description: 1. The L9110S is a dual Full H Bridge driver module designed for controlling stepper motors using Arduino or other microcontrollers. It supports both unipolar and bipolar stepper motors. 2. Each channel of the module can provide up to 1A continuous current, with a peak current capability of 2A, allowing it to drive various stepper motor sizes. 3. The L9110S features four independent microstepping modes: full-step, half-step, quarter-step, and 1/8th-step modes. These options offer greater precision and finer control over motor movement. 4. Integrated protection circuitry includes overcurrent protection (OCP), overvoltage protection (OVP), and short circuit protection (SCP) to ensure safe operation for the motors and other connected components. 5. The module communicates with the microcontroller via standard digital I/O pins, requiring only three wires for control: IN1, IN2, and EN. 6. It also comes with an optional external heatsink to help dissipate heat generated during continuo
