Installation Instructions
Default Program Description:
1.MFB rising edge of the boot, the falling edge of the shutdown (MFB power up after the pull can be done on the boot)
2. boot automatically into the back, even failure to automatically enter the pairing mode
3. Audio output mode has 3 options: analog output, I2S digital output, SPDIF fiber digital output
4. Support aptx, aptx-ll, aptx-hd, better sound quality!

Note
1. Module pin is more intensive, need a better welding machine foundation. 2. CSR Ble module audio for the differential output, you need to increase the op amp or amp circuit into single-ended output (left channel, right channel, audio common). 3. Only provide module application data, that is, Ble module specifications and Ble module reference schematics
