• Make some noise with your next project! The MP3 Trigger is a versatile, low-cost, low-power embedded audio unit that plays MP3 tracks directly from a FAT32 or FAT16 formatted microSD flash card to a stereo 1/8” (3.5mm) headphone output jack, supporting up to 192kbps stereo playback.
• The board has 18 external input pins that when pulled to ground, trigger pre-selected MP3 tracks, and a full-duplex serial control port that provides real-time volume control as well remote triggering for up to 255 tracks.
• There is also an on-board navigation switch for local access and playback of all MP3 tracks on the flash card.
• To get started with your MP3 Trigger, you'll need a few items not included. To begin, you'll need an microSD card on which to store your .mp3 files. A simple way to power the MP3 Trigger while you're familiarizing yourself with it is to use a 9V wall adapter. If you intend on using your MP3 Trigger with another serial device, you need an FTDI Basic or other serial connection.
• Last, you will need something though which to play audio. You may use headphones, a 3.5mm-to-3.5mm audio cable to connect to an external audio source, or one of our 3.5mm Audio pigtails to wire your MP3 Trigger to the output you desire.
