Make some noise with your next project! The MP3 Trigger board is built to make 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 can achieve 192Kbps stereo playback from a wider range of cards

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

This version of the MP3 Trigger includes firmware that supports the use of an initialization file on the microSD card that can be used to change the serial baud rate, as well as to repurpose any of the 18 trigger inputs to alternate functions, such as random and sequential triggers, navigation controls and even volume controls

In addition, a restart lockout option can be used to prevent any trigger from starting a track if audio is already playing

Using these features, custom applications can often be implemented without the use of a separate microcontroller
