This stepper motor control board with DRV8825 driver is the ideal solution for driving NEMA17-type motors in open-loop configuration. Built on a 4-layer PCB, it integrates both the DRV8825 driver and an ATmega32U4 microcontroller with Arduino Leonardo bootloader, programmable directly via USB without the need for external converters.

Designed to be mounted directly on the back of the motor, the board offers a plug-and-play solution perfect for robotics, CNC machines, DIY automation projects, and 3D printers. It supports microstepping up to 1/32 step, configurable via three DIP switches (M0, M1, M2), ensuring precise and flexible motor control.

The ATmega32U4 microcontroller can be programmed using the Arduino IDE, making it accessible even to hobbyists and beginners. Thanks to the Leonardo bootloader, programming is done directly via USB, just like a standard Arduino board.

Compact, versatile, and easy to use, this board is the perfect choice for those seeking an integrated, ready-to-use solution for stepper motor control.

Important note: The board is ready to use, with the Leonardo bootloader already loaded on the ATmega32U4.
