릴리패드형 MP3 재생기입니다.  오디오잭과 micro SD메모리 슬롯이 장착되었으며 3.5~6V의 외부 전원이나 3.7V Lipo 충전지로 구동 가능하며,  충전회로가 내장되어 FTDI USB to Serial 변환기 5V형을 연결해주시면 별도의 충전기기 없이 충전이 가능합니다. 

안내.  제품 구매시 MP3 보드만 발송 되며,   충전지, SD 메모리, 오디오케이블, 프로그래밍 및 충전용 FTDI USB to 시리얼 변환기 등은 미포함되었으며 별도로 구매하셔야합니다.

Description: The LilyPad MP3 Player is your all-in-one audio solution, containing an Arduino-compatible microcontroller, MP3 (and many other formats) audio decoder chip, micro-SD card socket, and a stereo audio amplifier. Part of the Lilypad E-textiles line, this board can be used to give your fabric creations the gift of music, or any other sounds you can put on a micro-SD card.

It can be powered by a 3.7V Lipo battery (charging circuit built-in!), or an external 3.5-6V source. Off the shelf, it will play specific audio files when any of its five trigger inputs are grounded, or you can solder in an RGB rotary encoder (not included) and load new firmware (included in the link below) to add a user interface for track selection and volume control!

The board is compatible with sketches written for the MP3 Player Shield. Our example code uses Bill Porter’s MP3 Player library, which makes writing new code very easy. All you need to do is add a microSD card and some speakers, and you’re ready to rock.

Note: A portion of this sale is given back to Dr. Leah Buechley for continued development and education of e-textiles and also to Arduino LLC to help fund continued development of new tools and new IDE features.
