**Note**

1. Since there is no lithium battery protection circuit on the decoder board, it is recommended to use this module with a Lipo Charger board.
2. Pay attention to the electrostatic protection. Since the Bluetooth chip is very sensitive to static electricity, you must discharge the static electricity on your hand to avoid causing damage to the chip when touching it with a bare hand.
3. Bluetooth antenna signal is easy to be influenced by high-frequency or strong electromagnetic signal, so please try to keep the module away from radio transmitting devices, and this board should not be placed close to any metal objects.
