We'll go over each pin on the board in the next page, right now let's look at the basic elements of the Sound Board so
you have an idea of what each piece does.
Starting from the left is the micro USB jack. You'll need a standard MicroUSB cable to connect this to your computer.
You do need a computer (any will do) in order to save files onto the Sound Board flash storage
This big chip is the audio decoding engine. It has OGG and WAV decoding capability and can listen to the trigger pins
to know when to play each file. It has great audio quality, much better than trying to have a microcontroller generate
the audio on its own.
It cannot decode MP3 files - but that makes it a lot less expensive since MP3 decoding requires a patent license where
as OGG and WAV are free for any kind of use.
