Interface Description:
1. Power supply can be provided by using Micro USB mobile phone charger, 3.7-4.2V lithium battery, 3.7-24V DC power supply, or any one of the three.
2. Short circuit the "on/off contact" for 2 seconds to set the decoding board on/off. For battery powered situations, shutting down when not in use is more energy-efficient and convenient for modification.

Operation Manual
After connecting the power, the blue indicator light flashes rapidly and enters Bluetooth mode; After broadcasting the "prompt sound", enter pairing mode and wait for pairing; Search for "XY-WRBT" (amplifier board device name) on the Bluetooth of your mobile phone, click on "XY-WRBT" to connect, and after successful connection, play a "prompt sound" with the indicator light on continuously to play music on your phone. When playing music, the indicator light flashes slowly; After disconnecting Bluetooth, the power amplifier board prepares for the next pairing and plays a "prompt sound" before entering pairing mode and waiting for pairing.
Precautions for using 3.7V lithium battery power supply
When using battery power, if the battery voltage is lower than 3.3V, the decoding board will automatically shut down. After re powering on or fully charging, short circuit the on/off contacts for 2 seconds to turn on.
When using battery power, if the battery voltage is too low, there may be "sizzling" noise, in which case the battery needs to be charged.
3. As there is no lithium battery charging protection circuit designed on the decoding board, it is recommended to use lithium batteries with built-in protection boards.
4. If your rechargeable battery supportsMicro USBIf charged directly, it can be usedMicro USBDirectly charge the battery.
