The rMP3 module allows designers to integrate high quality MP3 playback into designs with an easy to use TTL serial protocol.
Sound files such as voice prompts, sound effects, and music can be played using the rMP3. MP3 playback can be CBR (Constant Bit Rate), or VBR (Variable Bit Rate) up to 48 KHz at 320 Kbps. MP3 files are stored on SDHC, SD or MMC cards, in a format readable by your PC. PCM (WAV) files and IMA ADPCM files can also be played.
In addition to playing audio files, you can use the rMP3 for your data access applications as well. The rMP3 can create files and store data to SD or SDHC cards which can be removed, and read with any standard MMC/SD card reader on a PC. The rMP3 will read SD or SDHC cards in either FAT12, FAT16 or FAT32 formats in any size commercially available (8MB to 32GB).
Each module has a 1/8" stereo headphone jack for headsets (16 Ohms+) or for line-in connections. The rMP3 also has a multi-function 10-pin connector that allows direct operation of the module using simple logic triggers.
