Our existing Bluetooth amplifier boards support TWS or Party mode wireless pairing to link 2 or more boards together. However, the pairing process needs to press 3 buttons many times. This is not user-friendly for many new users. We have recently upgraded the AudioB I2S module to version 4, which supports a one-button pairing function. Users can upgrade the entire amplifier board by simply replacing the original AudioB I2S module with the latest v4 version.
Hardware Preparation:
Replace the old AudioB I2S module with AudioB I2S V4
Connect the RGB Push Button to the AudioB I2S V4
How to Use
TWS Firmware
Single module:
- Power on the module and wait for 5 seconds. The module will enter pairing mode, and the red and green LEDs will flash alternately.

- You can play music now
TWS Connection

- Pause the music, press and hold button S1 for about 2 seconds. You will hear two beep sounds, and the green LED will start flashing.
Slave module:
- Power on the other module (Slave) and wait for 5 seconds; the red and green LEDs will flash alternately.
