Note:

Noise may occur if the power supply battery voltage is too low, indicating the need for recharging.
Since the decoder board lacks a protection circuit for lithium batteries, it is recommended to use this module with a lipo charging board.
Be mindful of electrostatic protection. Since the Bluetooth chip is very sensitive to static electricity, discharge the static electricity from your hand to avoid chip damage when handling it with bare hands.
The Bluetooth antenna signal may be easily affected by high-frequency or strong electromagnetic signals, so keep the module away from radio transmitters and do not place this board near metal objects.
