The SparkFun MP3 Player Shield is an awesome MP3 decoder with the capabilities of storing music files onto a run-of-the-mill microSD card, thus giving you the ability toadd music or sound effects to any project. With this board you can pull MP3 files from an microSD card and play them using only one shield, effectively turning any Arduino into a fully functional stand-alone MP3 player! The MP3 Shield utilizes the VS1053B MP3 audio decoder IC to decode audio files. The VS1053 is also capable of decoding Ogg Vorbis/MP3/AAC/WMA/MIDI audio and encoding IMA ADPCM and user-loadable Ogg Vorbis.
The VS1053 receives its input bitstream through a serial input bus (SPI). After the stream has been decoded by the IC, the audio is sent out to both a 3.5mm stereo headphone jack, as well as a 2-pin 0.1" pitch header.
This shield comes populated with all components as shown in the images and schematic; but it does not come with headers installed. We recommend the Arduino R3 Stackable Header Kit.

在SparkFun MP3播放器盾是一個真棒MP3解碼器與存儲音樂文件到運行中的磨microSD卡,從而給你TOADD音樂或音效任何項目的能力的能力。本主板你可以從一個microSD卡拔出MP3文件,並只使用一個盾,有效地將所有的Arduino成為一個功能齊全的獨立的MP3播放器播放他們!該MP3盾利用VS1053B MP3音頻解碼芯片解碼音頻文件。在VS1053還能夠解碼的Ogg Vorbis / MP3 / AAC / WMA / MIDI音頻編碼和IMA ADPCM和用戶加載的Ogg Vorbis的。
所述VS1053通過串行輸入總線(SPI),接收它的輸入比特流。流已經由IC解碼之後,音頻被發送到這兩個3.5mm立體聲耳機插孔,以及一個2針0.1“間距頭。
這盾置有作為圖像和原理圖中顯示的所有組件;但它沒有附帶安裝頭。我們推薦的Arduino R3可堆疊頭套件 。
