SparkFun MP3 Trigger

Regular price $0.00 $41.87 Sale

Key Features

  • Built to make MP3 sound integration easier than ever
  • Cypress PSoC CY8C29466-24SXI microcontroller serves up MP3 data to a VLSI VS1063 audio codec IC
  • New trigger filename convention provides greater flexibility in naming your MP3 tracks - making file management easier
  • “Quiet Mode” feature enabled via the serial control port don’t start tracks directly

The MP3 Trigger 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. It supports an optional initialization file 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.
