DRV8825 Stepper Motor Shield

thingiverse

This dual stepper motor shield for Arduino is designed for the DRV8825. The DRV8825 is commonly used as stepper drivers for 3D printers. The DRV8825 has an adjustable current control to set the max current output to the motors. Refer to the Pololu web site for driver details and instructions on setting motor current: https://www.pololu.com/product/2133 The 3D printed sheld has all the holes positioned to insert the components as shown in the pictures. Components needed to build this shield: 2 DRV8825 Stepper Motor Drivers (Amazon) 2 100 uF Electrlitic Capacitors (Adafruit https://www.adafruit.com/product/2193) 5 Screw Terminals 0.2 in pitch (Radio Shack) 6 Sets of 3 Male .1 in pitch headers (Adafruit https://www.adafruit.com/product/392) 1 Set of Arduino Stacking Headers (Adafruit https://www.adafruit.com/product/85) 3 Jumpers 0.1 in pitch Hookup Wire (I used wire wrap wire) Note: Use wire for motors that are rated for the motor amperage.
