The board is designed for beginners in Arduino, with various components available that makes you build more than 10 projects easily. You won’t have to solder or connect anything at all, just plug it in a shield and start coming up with various simple examples rather than dealing with cables, sensors and breadboard. Next to each component you can see the digital on analog pin it is connected to. Also there are couple of digital pins and one analog pin available for other projects. This shield can be fully compatible with the Arduino UNO R3 and it will never short circuit with the Arduino UNO USB interface, so it is very safe.
