Description 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. Key Features Model: DRV8825 Step stick Stepper Motor Driver Input Voltage: 8.2V – 45V DC Max Current: up to 2.2A per coil (with cooling) Micro stepping: Full, 1/2, 1/4, 1/8, 1/16, 1/32 Over-temperature & over-current protection Compatible with RAMPS 1.4, Arduino, and other CNC controller boards Drop-in replacement for A4988 stepper driver Applications 3D printers (RepRap, Prusa, Reality upgrades) CNC machines and laser engravers Robotics and automation projects DIY electronics requiring stepper motor control
