Adafruit原廠「Music Maker」MP3 Shield模組 For Arduino（ada1790）不含端子頭
「Music Maker」分２板：含端子頭、不含端子頭
這個版本的屏蔽只有立體聲線路/耳機輸出（沒有放大器的版本）。
Each order comes with one fully-assembled and tested shield, 2 2-pin terminal blocks, a stick of 0.1" male header and 2x3 female header for the ICSP connection. Some light soldering is required to attach the through-hole headers to the PCB for plugging into the Arduino as well as the terminal blocks for the speakers. Speakers, headphones, SD card and Arduino not included!
每個訂單都附帶一個完全組裝和測試的屏蔽罩、2 個 2 針接線端子、一根用於 ICSP 連接的 0.1" 公接頭和 2x3 母接頭。需要一些輕微焊接才能將通孔接頭連接到 PCB 用於插入 Arduino 以及揚聲器的接線端子。
不包括揚聲器、耳機、SD 卡和 Arduino！

＊修訂記錄：2014 年 9 月 22 日：我們更新了模擬部分以提供更多濾波，這應該會提高音頻輸出質量（甚至更多！）沒有佈線或代碼更改。
＊尺寸：69mm x 53mm x 2mm / 2.7" x 2.1" x 0.8"

This version of the shield only has stereo line/headphone output. We also have a version with a 3W/channel class-D stereo speaker amplifier for easy use in projects that need to be loud／這個版本的屏蔽只有立體聲線路/耳機輸出（沒有放大器的版本）。
我們還有一個帶有 3W/通道 D 類立體聲揚聲器放大器的版本，便於在需要大聲的項目中使用。
We believe this is the best MP3 playing shield you can get, and at a great price too. Here are some specs:
- Features the VS1053B codec chip - decodes Ogg Vorbis, MP3/MP2/MP1, MP4, AAC, WMA, FLAC, WAV/PCM, MIDI. Encodes Ogg or WAV/PCM
- Stereo audio out with proper audio filter caps and ground reference so it can be safely connected directly to headphones, a stereo system or other powered speakers
- 7 extra GPIO's that can be written or read through the Arduino Library for reading buttons or lighting LEDs
- MicroSD card socket, for any FAT16/FAT32 formatted SD card from 64Mb or greater.
- Full 3.3/5V level shifting for SD and MP3 chipsets
- Works with Arduino Uno, Mega, or Leonardo
- Built in MIDI synth/drum machine with dozens of instruments
- Plenty of optional breakouts for pins like the card-detect and microphone input
Description
Bend all audio files to your will with the Adafruit Music Maker shield for Arduino! This powerful shield features the VS1053, an encoding/decoding (codec) chip that can decode a wide variety of audio formats such as MP3, AAC, Ogg Vorbis, WMA, MIDI, FLAC, WAV (PCM and ADPCM). It can also be used to record audio in both PCM (WAV) and compressed Ogg Vorbis. You can do all sorts of stuff with the audio as well such as adjusting bass, treble, and volume digitally.
All this functionality is implemented in a light-weight SPI interface so that any Arduino can play audio from an SD card. There's also a special MIDI mode that you can boot the chip into that will read 'classic' 31250Kbaud MIDI data from an Arduino pin and act like a synth/drum machine - there are dozens of built-in drum and sample effects! But the chip is a pain to solder, and needs a lot of extras. That's why we spun up the best shield, perfect for use with any Arduino Uno, Leonardo or Mega.
