DRV8825 Stepper Motor Driver Module

Overview 

The DRV8825 is a high-performance carrier board for TI’s DRV8825 stepper motor driver. It is widely considered the “Pro” version of the A4988. It features adjustable current limiting, over-current and over-temperature protection, and six microstep resolutions (down to 1/32-step). If your motors are getting hot or making too much noise with an A4988, the DRV8825 is the solution to make your CNC or 3D printer run like a dream.

Key Features 

• Higher Microstepping: Supports 1/32 step mode, allowing for much finer precision and quieter motion than the A4988’s 1/16 limit.

• Increased Power: Can handle up to 2.5A per coil (with sufficient cooling), making it ideal for larger NEMA 17 motors.

• 4-Layer PCB: Designed with a 4-layer copper PCB to improve heat dissipation and durability.

• Drop-in Compatible: Has the same pinout as the A4988, meaning it works perfectly with RAMPS 1.4, CNC Shields, and MKS boards.

• Built-in Regulator: Operates logic at both 3.3V and 5V, so it’s compatible with both Arduino and ESP32/STM32.
