## Description

A4988 or DRV8825 driver expansion board, ideal for Arduino UNO R3 and 3D printers, facilitates the control of Nema17 stepper motors in DIY projects. Offers DIP switch for quick microstep setting, terminal connector for easy power supply, compatibility with 12 24VDC and DIR STEP EN interfaces to 5V logic. Correct connection of driver polarity and orientation.
Stepper motor driver expansion board designed to be used with Arduino UNO R3 and 3D printers. Its features include an integrated DIP switch, which allows easy adjustment of driving segments, and a terminal power connector for easy connection of drive power. It is compatible with 12/24VDC actuation schemes and is suitable for controlling 42mm Nema17 type stepper motors, being ideal for 3D printing applications and DIY projects.
Pay attention to the polarity and the direction of the driver, the wrong connection may lead to the burning of the extension board but also to the burning of the motor driver.
