After getting the Bluetooth board, refer to the wiring diagram below to solder the speaker and 3.7V lithium battery, and then check that the battery is not connected reversely. You can turn on the power test. Turn on the switch and the blue indicator light should light up.

If it does not light up, you should quickly turn off the power to check whether the battery is installed correctly. When the indicator light is on and there is a ding-dong prompt sound, you can turn on the mobile phone Bluetooth to refresh the Bluetooth name, find "DAU Audio" to connect and play the music on the mobile phone.

Regarding TWS pairing, if you buy two DAU Audio Bluetooth modules, they can be paired in stereo. You need to turn off the Bluetooth of your mobile phone first, then turn on both boards at the same time, wait for a few seconds to hear the prompt tone, then the blue indicator light of one module is always on, and the indicator light of the other module is still flashing, indicating that the TWS pairing is successful.

Then turn on the mobile phone to connect Bluetooth, and you will have a stereo wireless speaker. It is recommended to use a 500mAh-2000mAh capacity 3.7V lithium battery, and a 5V 1A-2A charger, and use a USB2.0 to Type-C cable for charging.
