Make a splash in your next project with the MP3 Trigger Board! This amazing board is designed to make integrating MP3 sounds a breeze. It comes with 18 external trigger pins that can directly play pre - selected MP3 tracks. There's also a full - duplex serial control port for complete transport control, remote triggering of up to 256 tracks, and super - fast real - time volume adjustment. Store your MP3s on FAT16 formatted SDSC or FAT32 formatted SDHC micro - SD flash memory cards, and thanks to optimized code, enjoy 192Kbps stereo playback from a wide range of cards. The heart of this board is the Cypress PSoC CY8C29466 - 24SXI microcontroller, which feeds MP3 data to a VLSI VS1063 audio codec IC. This version supports an optional initialization file. You can use it to set the serial port baud rate and reprogram the 18 trigger inputs for alternate functions like random and sequential track selection, transport controls, and volume adjustment. Each trigger can be set to allow immediate restarts or lock them out when audio is playing. A new trigger filename convention gives you more flexibility in naming MP3 tracks and simplifies file management. There's a 'Quiet Mode' that you can enable via the serial control port. In this mode, trigger inputs send serial messages instead of directly starting tracks, letting a host microcontroller manage track playback and making triggers highly flexible. The included firmware supports an initialization file on the microSD card, allowing you to change the serial baud rate and repurpose trigger inputs. A restart lockout option stops triggers from starting new tracks when audio is playing. These features often let you implement custom applications without an extra microcontroller. Note: This product is a collaboration with Robertsonics, and a portion of sales goes back to them for support and development. Features: Input Voltage Range: 4.5V to 12.0V DC, or regulated 3.3V (jumper selectable); Current Consumption: About 45mA idle, 85mA playing; Media: SDSC and SDHC microSD cards; File system: FAT32 and FAT16; Audio output: Headphone stereo (1/8” stereo jack); Trigger inputs: Logic level 3.3V–5.0V, active low inputs, w/ internal pull - ups; Serial: Full duplex, 8 - bit, 38.4Kbaud (default, other baud rates supported via initialization file).

Using the MP3 Trigger Board is quite straightforward. First, make sure to choose the right power source. You can select between a 4.5V to 12.0V DC input or a regulated 3.3V by using the jumper. Then, insert your micro - SD card formatted in either FAT16 or FAT32, which should have your MP3 files stored on it. To play specific tracks, you can use the 18 external trigger pins. Just connect a switch or jumper to the trigger input, and it'll play the pre - selected track. If you want more control, use the full - duplex serial control port. You can set up the serial port baud rate and other functions using the optional initialization file on the microSD card. For example, you can change trigger inputs to do things like random track selection. When using the 'Quiet Mode', enable it via the serial control port. In this mode, the trigger inputs will send a message to a host microcontroller, which can then start the tracks you want. This gives you more flexibility in how you play your tracks. As for maintenance, keep the board clean and free from dust. Make sure the micro - SD card is inserted properly to avoid data read issues. If you're having trouble with the board, check the provided documents like the schematic and datasheets. Also, remember that a portion of the sales of this product goes to Robertsonics for support and development, so if you have any product - related questions, you can refer to the MP3 Trigger Support Page. And don't forget to check for firmware updates on the provided links to keep your board up - to - date.
