The DRV8825 stepper motor driver carrier is a breakout board for TI’s DRV8825 micro-stepping bipolar stepper motor driver. The Stepper Driver module has a pinout and interface that are nearly identical to those of our A4988 stepper motor driver board, so it can be used as a higher-performance drop-in replacement for those boards in many applications. The DRV8825 Arduino stepper motor controller features adjustable current limiting, over-current, and over-temperature protection, and six micro-step resolutions (down to 1/32-step). It operates from 8.2 – 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling).

Arduino Nano V3 is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3. x). Arduino Nano board has more or less the same functionality as the Arduino UNO but in a different package. Arduino Nano programming module lacks only a DC power jack and works with a Mini-B USB cable instead of a standard one.
