You will also need a Micro USB Cable (not included) to load the sounds to your MP3 board. Alternatively you can play them directly from a microSD card (not included) inserted into the board. If your computer doesn't have a MicroSD card reader/writer then this inexpensive microSD USB Reader and Writer will do.
