MP3 Trigger

$49.95

Created in collaboration with Jamie Robertson, the MP3 Trigger is quite possibly the most versatile, low-cost, low power embedded MP3 Player. 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. The board plays the MP3 files directly from a FAT16 microSD flash card and supports 192Kbps stereo playback. There is also an on-board navigation switch for local access and playback of all MP3 tracks on the flash card.

New for Version 2: Aside from more than doubling the number of trigger inputs, the MP3 Trigger v2 now contains a resident bootloader that enables firmware updates directly from the microSD card without requiring a hardware programmer. The PSoC Designer IDE can be used to generate hex files for the bootloader. See the datasheet below for more details on how to use the bootloader.

The board uses a Cypress PSoC CY8C29466-24SXI microcontroller and a VLSI VS1053 audio codec.

Board can be powered by an external wall wart, FTDI Basic, or raw 3.3V input.

Features:

  • Input voltage: 4.5-12VDC
  • Current Consumption: 45mA idle, 85mA playing
  • File system: FAT16
  • Audio out: line level stereo (1/8" stereo jack)
  • Trigger inputs: 3.3-5V, active low inputs with internal pull-ups
  • Serial: Full duplex, 8N1, 38.4K baud
