There are five areas on the Little Soundie that allows you, the user, to interact with the board, the

Power/Play button, the trigger pins, the 3.5mm jack and micro-USB port, and the VSIDE pins and

each of these areas provide different functions for operation. The Power/Play button is pretty much

what it says it is, it turns on the VS1000D which then triggers all the internal voltage regulators. The

trigger pins on the left side of the board activate each track on the Little Soundie based on a binary

code while a momentary connection to 3.3V will trigger the audio to playback (we go into good detail

about this in the Hookup Guide below). The 3.5mm jack and micro-USB connector provide your

input and outputs for the board. Finally on the right side of the board are the VSIDE UART

programming pins which allow you to change or add any functionality of the Little Soundie through

the IDE.

Note: Speakers are required for the Little Soundie, not headphones. Headphones won’t break

anything but you won’t get any sound either.
