PA213 Bluetooth 5.0 Module CSR8675 Module Bluetooth Audio Module I2S/ SPDIF Output BTM875-B
Description:
BTM875-B Bluetooth module is designed without antenna. It supports differential analog audio output and I2S digital/ SPDIF digital output. It is welded and ready to use.
For CSR8675 Bluetooth module, the high level of I2S digital output signal is 3.3V. The analog output is a differential signal, that is, a balanced output. If your amplifier does not support differential inputs, you need to convert it to a single-ended output.
Functions:
- BTM875-B Bluetooth module (CSR8675 Bluetooth chip).
- With detailed pin description for reference.
- Pin hole is a standard 2.54mm pitch for easy welding and debugging.
- Integrates indicators LED0 and LED1.
- MFB delay circuit when it is powered on. It can be used when powered.
- The voltage of VDD is 3.3V-5V. The maximum voltage can not exceed 6V.
- For SPDIF output, DATA is the SPDIF_OUT output pin.
- For I2S output, it can be used with our DAC decoder board, of which the pins match.
- Board size 24 x 36.5mm
Package Included:
- 1 x Bluetooth 5.0 Audio Module Board
Optional Types:
- Type A: CSR8675 Module I2S+Differential Output Firmware
- Type B: CSR8675 Module SPDIF+Differential Output Firmware
Note: Please choose the type you want when purchasing. Thank you!
