SparkFun Electronics will be closed in observance of memorial day on Monday, May 29th. We will resume normal business hours on Tuesday, May 30th. Any orders placed after 2pm Mountain Time on Friday, May 26th will process and ship out on Tuesday, May 30th.
This is a retired product. There is an updated version available: WIG-13720
Description: Replacement:WIG-11029. The new version of this board replaces the VLSI VS1053 with the VS1063, there are also several firmware changes and improvements. This page is for reference only.
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.
Firmware version 2 also incorporates “Quiet Mode”, a new feature that can be enabled via the serial control port. In this mode, the triggers don’t start tracks directly, but instead produce a serial message indicating which triggers were activated. A host microcontroller (Arduino, for example) 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.
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 (see related items below).
Firmware update 2.40 Beta: Check it out here and be sure to leave feedback on the blog post.
Firmware update 2.23: compatible with 192kbps audio.
We use the most up-to-date firmware on everything we ship out. However, if you have an older v2.xx model (or want to change the baud rate) and wish to have the newest firmware, you can get it here.
Instructions on how to update your v2.xx firmware are in the datasheet, but here’s a quick review:
Please refer to the datasheet for a more detailed description of the Status LED indications when running the bootloader.
Note: This product is a collaboration with Jamie Robertson. A portion of each sales goes back to them for product support and continued development.
