StepStick DRV8825 Stepper Motor Driver for 3D Printer & CNC

StepStick DRV8825 Stepper Motor Driver for 3D Printer & CNC

The StepStick DRV8825 Stepper Motor Driver is a high-performance driver board designed for 3D printers, CNC machines, and engraving equipment. Compared to the A4988 driver, the DRV8825 offers higher current handling, up to 2.5A, and supports up to 1/32 microstepping, allowing smoother and more precise motor control.

Built with a 4-layer PCB for superior heat dissipation, the DRV8825 ensures stable performance even under heavy loads. It features overheat shutdown, undervoltage lockout, and short-circuit protection, making it reliable and safe for continuous operation. Its compact size is identical to the A4988, ensuring easy replacement or upgrade.

This driver is widely compatible with popular 3D printer models such as Prusa Mendel, Ultimaker, MakerBot, and Printbot, as well as CNC routers and engraving machines. With adjustable current control and multiple stepping modes, the DRV8825 is the perfect choice for makers, hobbyists, and engineers looking for precision, durability, and efficiency.

Relative to the 4988 features:

1. The maximum current is 2.5A.

2, the highest support for 32 subdivisions.

3, 4 layer PCB board, better heat dissipation performance.

4, the chip internal resistance is smaller, lower heat, better heat dissipation.
