Shield Reproductor MP3 de Sparkfun
Ofrece un conector de salida de audio de 3,5 mm
Conector espaciado de 0,1 pulgadas para salida de altavoz
Cuenta con una ranura para tarjeta microSD
El Shield Reproductor MP3 de Sparkfun es un decodificador de MP3 con la capacidad de almacenar archivos de música en una tarjeta microSD corriente, lo que le brinda la posibilidad de agregar música o efectos de sonido a cualquier proyecto. Con esta placa puede extraer archivos MP3 de una tarjeta microSD y reproducirlos usando solo un shield, convirtiendo efectivamente cualquier Arduino en un reproductor MP3 autónomo completamente funcional.
El Shield MP3 utiliza el decodificador de audio MP3 VS1053B para decodificar archivos de audio. El VS1053 también es capaz de decodificar audio Ogg Vorbis/MP3/AAC/WMA/MIDI y codificar IMA ADPCM y Ogg Vorbis cargable por el usuario.
El VS1053 recibe su flujo de bits de entrada a través de un bus de entrada serial (SPI). Una vez que el IC ha decodificado la transmisión, el audio se envía a un conector para auriculares estéreo de 3,5 mm, así como a un conector de paso de 2 pines de 0,1 pulgadas.
Este shield viene poblado con todos los componentes como se muestra en las imágenes y el esquema, pero no viene con los headers instalados.
Shield is good, documentation link needs to be updated
I got this for sound for a robot project. I had a frustrating experience trying to use the example in the documentation link. The libraries used by the examples have changed and are no longer compatible. Robot Shop: please update the link. Once I found the updated Sparkfun documentation at https://learn.sparkfun.com/tutorials/mp3-player-shield-hookup-guide-v15?_ga=2.91878362.1511680999.1640800548-620763291.1637437471 and libraries and example code at https://github.com/madsci1016/Sparkfun-MP3-Player-Shield-Arduino-Library, I was able to get it to work, and it does work well. I was using external speakers (a small "sound bar" for a laptop), so I needed to unsolder and re-solder the jumpers SJ3, SJ4 and SJ5 to avoid a nasty buzzing. After that, the sound was good. One problem I had was when I hooked up a button to pin 10 (which should be free), the arduino would hang when pin 10 was connected to ground. I don't know what that was about, but ended up using one for the A pins (digital pin 15) instead and it solved my problem. Comment RobotShop: Thank you, Ian. We updated the product description and useful documents.

Nifty sound output shield.
Audio quality was absolutely excellent with more than enough control over sound characteristics for my needs. Only small disappointment is the lack of mounting holes, otherwise 5/5. Great service from Robotshop as well.
