20 or more $10.45
If you want to build a digital Bluetooth amplifier board. AudioB I2S Bluetooth audio receiver module is a good choice for your project. This is a Bluetooth 5.0 stereo recevier module, I2S digital output and music resampling frequency is 48KHz. It supports Apt-X, and is based on CSRA64215. We breakout pins to 2x10 2mm space male pins. You can integrate it to your project easily. This module has a SMA connector. You can connect an external 2.4G antenna with it.
If you want a demo board. Please buy our TSA7010 Digital Bluetooth Audio Receiver. It's a AudioB I2S module + DAC board.
The module PIN7,8,9,10 are I2S output pins, I2S voltage 1.8V.
- 7 - GND
- 8 - BCK I2S synchronous data clock, It's a 2.304MHz square wave signal.
- 9 - SD I2S synchronous data output.
- 10 - LRCK I2S word select, 48KHz. 1 - Left channel data, 0 - Right channel data.
- Setting switch: We set to I2S in normal state. Set to SPI when you need to program the module.
Note1: You need to set the on-board switch to SPI when you program the module
Note2: You need change this module from I2S master to I2S slave, if you want to use it on our digital audio amplifier boards.
