DRV8825 Stepper Motor Driver – Step stick for 3D Printer CNC

The DRV8825 Stepper Motor Driver is a high-performance step stick module designed for controlling bipolar stepper motors in 3D printers, CNC machines, and robotics projects. Built around the Texas Instruments DRV8825 chip, this driver provides precise motion control with up to 1/32 micro stepping for smooth and quiet operation.

Compared to the A4988 driver, the DRV8825 can handle higher current, support wider input voltages, and offers improved thermal performance. This makes it a popular choice for upgrading RepRap 3D printers, CNC routers, and DIY robotics projects.
