The uMP3 is a versatile, low power embedded MP3 player which allows designers to integrate high quality MP3/PCM/WAV/IMA ADPCM playback into designs.
The module has 8 external trigger pins which can be used to trigger MP3 tracks off of the SD/SDHC/SDXC card. The uMP3 also has a 7 bit digital interface mode which allows extremely simple triggering of up to 127 different tracks.
The serial interface allows full control of all playback features, as well as all file functions available on the uMMC Data Storage Module. This means you can play audio tracks and store/read data simultaneously.
Each module has a 1/8" stereo headphone jack for headsets (16 Ohms+) or for line-in connections.
For 7-12 volt operation (especially for standalone applications), we recommend using the Rogue Robotics rPower board.
Firmware can be updated, as new features become available, through the serial interface.
SD/MMC card not included.
