Noise may occur when the power supply battery voltage is too low, indicating that it needs to be charged.
Since there is no protection circuit for lithium batteries on the decoder board, it is recommended to use this module with a Lipo charging board.
Pay attention to electrostatic protection. Since the Bluetooth chip is very sensitive to static electricity, you must discharge static electricity from your hand to avoid damaging the chip when handling it with bare hands.
The Bluetooth antenna signal can be easily affected by high-frequency or strong electromagnetic signals, so please keep the module away from radio transmitters and do not place this board near metal objects.
