This module is designed to drive stepper motors. It uses DRV8825 chip and has a maximum driving current of 2.5A. The DRV8825 is a complete micro-stepping motor driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full, 1/2, 1/4, 1/8/ 1/16, or 1/32 step modes. We add an on-board potentiometer, so you can change the current of motor easily.
• Compatible with 4 wire bi-polar stepper motors;
• A potentiometer to control the current of the stepper motor;
• A on board heat sink helping heat dissipation;
• Capable of driving one stepper motor (green interface);
• Color-code male and female pins ensure connecting with MegaPi correctly;
• Small size for easy connecting with MegaPi.
• Motor driver: DRV8825
• Output current：1.75A (with proper heatsinking at 24 V and 25°C）
• Max current: 2.5A (pay attention to heat dissipation)
• Drive voltage: 8.2V-45V
• Note: MegaPi max supply voltage 12V
• Logic voltage: 5V
• Dimensions: 1.5cm x 2.0cm

DIY CAMERA SLIDER
Have you ever imagined that you can also DIY your own camera slider? Yes, you saw it right! You just need several beams, a stepper motor, a MegaPi to build the main part, then a synchronous belt, and now your camera slider is done. As you see, the camera is fixed on the camera slider to take photos of the scene in front of it. Wow, it is so cool, isn't it?
