# A Simple SdFat Audio Player

The example demonstrates how to implement an __MP3 Player__: which provides the data from a SD drive and provides the audio via A2DP (e.g. to a Bluetooth Speaker): The __AudioSourceSdFat class__ builds on the [SdFat Library](https://github.com/greiman/SdFat) from Bill Greiman which provides FAT16/FAT32 and exFAT support. 

## SD Card

Here is the information how to wire the SD card to the ESP32

| SD    | ESP32 
|-------|-----------------------
| CS    | VSPI-CS0 (GPIO 05) 
| SCK   | VSPI-CLK (GPIO 18) 
| MOSI  | VSPI-MOSI (GPIO 23) 
| MISO  | VSPI-MISO (GPIO 19) 
| VCC   | VIN (5V)
