1. Use BTM875-B Bluetooth module (CSR8675 Bluetooth chip)

2. The module picture already has a description of the foot position. Please refer to the module picture

3. The row pin hole is standard 2.54mm spacing, which is convenient for welding and debugging

4. The board has integrated LED0 and LED1 indicator lights

5. Integrated MFB power on delay circuit, power on to use

6. The VDD power supply voltage is 3.3V-5V, and the maximum voltage cannot exceed 6V!

7. When SPDIF is output, data is the SPDIF OUT output pin!

8. I2S output can be used with DAC decoding board

9. Board size: 30 * 38mm (excluding the protruding part of SMA head)

10. This product does not have antenna. Antenna needs to be purchased separately. SMA head and module shall be welded before shipmen

 

In addition: the high level of I2S digital output signal of CSR8675 Bluetooth module is 3.3V! The analog output is a differential signal (i.e. balanced output). If the power amplifier doesn't support differential input, it needs to be converted to a single end output.

 

 

 

Description of audio output mode:

1. Four kinds of internal firmware:I2S digital + differential analog audio output ,   SPDIF digital + differential analog audio output,I2S+LDAC,SPDIF+LDAC
 
2. LDAC only supports digital output, no differential analog output!
 
3. LDAC supports both aptxhd and LDAC formats!
 
4. The chip of LDAC has been encrypted and cannot be programmed with SPI.
