Stereo Audio MP3 Player Shield with USB microSD 3W Amplifier for Arduino
If you need to play MP3 files directly from a USB stick - the Stereo Audio MP3 Player Shield with USB microSD 3W Amplifier for Arduino from PMD Way solves your problem.
This is a fully-assembled MP3 shield for Ardino with both a microSD card AND a full USB socket interface - and you can also copy MP3 audio files to the onboard 64 Mbit flash memory. Both FAT16 and FAT32 file systems are supported.
You can listen to the audio through the 3.5mm stereo headphone socket, or connect speakers to the onboard 3W/4 ohm stereo amplifier.
The MP3 player can be controlled via your Arduino and the TTL serial - or the convenient buttons on the shield as shown in the images.
Shield supports 16~320Kbps MP3 files and 8~44.1 kHz WAV files.
