Description: Make some noise with your next project! The MP3 Trigger board is built to make it MP3 sound integration easier than ever. The board has 18 external trigger pins that will directly trigger pre-selected MP3 tracks, and a full-duplex serial control port that provides full transport control, remote triggering for up to 256 tracks, and fast real-time volume control. MP3s are stored on FAT16 formatted SDSC or FAT32 formatted SDHC micro-SD flash memory cards. In addition, optimized code now achieves 192Kbps stereo playback from a wider range of cards than before.
The heart of the MP3 Trigger board is the Cypress PSoC CY8C29466-24SXI microcontroller which serves up MP3 data to a VLSI VS1063 audio codec IC. This version also supports an optional initialization file that can be used to set the serial port baud rate as well as to reprogram any of the 18 trigger inputs to alternate functions, including random and sequential track selection, transport controls and even volume up/down. Each conventional trigger can be set to either allow immediate restarts, or to lock out restarts if audio is playing. Also, a new trigger filename convention provides greater flexibility in naming your MP3 tracks and makes file management easier.
There is also a “Quiet Mode” feature that can be enabled via the serial control port. In this mode, the trigger inputs don’t start tracks directly, but instead produce a serial message indicating which triggers were activated. A host microcontroller can thus monitor the trigger inputs and then start any track or sequence of tracks via the serial control port, making the triggers much more flexible.

used this with the spark fun amplifier kit for my full size r2 unit, sounds great, thanks
I used this to add custom audio to a pinball machine. Set up was very quick & easy. You’ll need to provide your own dc power supply, micro sd & pre amp. Works flawlessly!
I use the MP3 Trigger in a product called, “Digital Toy Counter”. It is a device that allows a theater organist to activate various fun sounds such as train whistle, rain and thunder, etc. The original theater organ toy counter was a bunch of sound-making devices attached to a wind way. Devices such as agooga horn, cymbal, drum, etc. That is why it was called a Toy Counter, a countertop where all the toy sounds were located. I sell it through Cinnamonhillart.com.
I use this product to play safety announcements at theme parks & go Kart tracks in our own DSA-4M self contain system. This MP3 Trigger is the heart of our system. Not only sound great, but works great also. We use this unit as trigger, as a sequencer, sequence with a timer, & run off solar power when needed. If a trigger MP3 player is needed, this is the one to get, this is a great product. Thank You Sparkfun….
