DRV8825 Stepper Motor Driver for Keyestudio 3D Printer

This DRV8825 Stepper Motor Driver, from Keyestudio, is a module designed to control stepper motors in 3D printers. It works with a power supply of 8.2 to 45 V and can provide up to approximately 1.5A per phase without a heat sink or forced air. Its interface and pinout are virtually identical to the A4988 stepper motor driver, so it can be used as a high-performance replacement in many occasions.

Features

1. Suitable for driving stepper motors within 8.2V~45V 2.5A；
2. Simple step and direction control interface;
3. Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step;
4. Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor's rated voltage to achieve higher step rates
5. Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay);
6. Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout;
7. Short-to-ground and short-load protection.
