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.

Note: The MP3 Trigger supports both SDSC (up to 2GB) and SDHC (up to 32GB) type microSD cards.
Note: This product is a collaboration with Robertsonics. A portion of each sales goes back to them for product support and continued development.
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Rookie - The number of pins increases, and you will have to determine polarity of components and some of the components might be a bit trickier or close together. You might need solder wick or flux.

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

used this with the spark fun amplifier kit for my full size r2 unit, sounds great, thanks
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….
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!
This product brings joy to my kid and a lot of peoples. Easy to set it up.
Randomness factor could be improved. Should allow organizing mp3 files into folders Should allow total random selection of mp3 files across folders.
It works as advertised, documentation on the product is very poor. You just need to figure things out on your own.
Hi, Did you see the user guide? It’s a pretty solid document in helping get started - http://cdn.sparkfun.com/datasheets/Widgets/MP3%20Trigger%20V2.5%20User%20Guide%202012-02-01.pdf
Not sure why they had the skills-required rated as high as they did.. I just added a push button and changed one line of code in a pre-made config file they provided, seems pretty simple to me. I like it!
OK, so now that we are trying to use it “for real” and more often, there seems to be a problem. I have a push-button switch on one of the triggers; when pushed it should sound a random one of the five songs on the card. Some of the time this works. At other times, all that happens is a very short flash of the green status light. Is anyone else encountering this?
This product did what it was supposed to do. I tried to get help with writing the INIT file on the forum, but I have not been able to get any help.
I am using the MP3 trigger to provide music for a miniature carousel. It works great, and gives us a convenient way of selecting which music to play. It was easy to set up, and the default settings are just fine for our uses.
