Description
The DRV8825 Stepper Motor Driver is a high-performance microstepping driver for bipolar stepper motors. It is designed as a drop-in replacement for A4988 drivers and offers improved performance with higher current capability and finer microstepping resolution (up to 1/32-step). It includes built-in protection features such as thermal shutdown, over-current protection, and short-circuit protection, making it highly reliable for 3D printers and CNC machines.

This module allows users to adjust current limiting via a potentiometer, enabling stepper motors to operate at higher voltages for improved speed and torque. The intelligent chopping control automatically selects the best current decay mode (fast decay or slow decay), ensuring smoother motor operation.

Ideal for 3D printers, CNC machines, and other precision motion applications, the DRV8825 driver is a robust and efficient solution for stepper motor control.
