Give your projects a voice (or music or sounds)

Posted on 08. Nov, 2009 by in Misc Modules

Some projects just scream-out for a bit of audio. Whether it's an alarm you want to speak a warning, a LED game that needs some bleeps and bloops, or whatever, this MP3 trigger module will get the job done.

This tiny module features a Cypress PSoC CY8C29466-24SXI microcontroller and a VLSI VS1053 audio codec. There are seven inputs that you can use to trigger particular sounds to be played directly. In addition, there is a serial communication port which can be used to play any of up to 256 sounds and also adjust the volume in real-time. Sounds stored on a FAT16 MicroSD card, so it's super easy to load your sounds and update them as your project develops.

Some features of the MP3 Trigger module include:

  • 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

Grab this easy-to-use handy MP3 Trigger module for around $50 and give that project the voice it deserves!
