XC4472 User Manual
Overview
This motor controller shield sits directly on top of the UNO layout. It has 2× 5V Servo ports, 4 Bi-Directional DC Motor ports with 8-bit speed resolution. Alternatively, it can control 2 Stepper motors using 2 motor ports per Stepper.

If you are using a different type of motor, such as a 12V motor; you will have to connect 12V into the EXT Power screw terminals found on the side of the shield. By default, the shield is configured to run the Arduino off this power source as well.Please note, if you need to connect more than 12v, you must disconnect the power feed jumper and power the Arduino through some other means. UNO cannot handle 12V.

Source code
The code for this shield is mainly handled by the “Adafruit Motor Shield” Library, you will not need to manually manage different pin configurations to use this shield. A basic sketch file is presented below, with a basic DC motor attached to M1 on the Motor shield.
