Note:
- The decoder board automatically turns off when the supply battery voltage drops below 3.3V. It can be turned on by replacing the battery or short-circuiting the on/off contacts for 2 seconds if the current battery is fully charged.
- Noise may occur when the supply battery voltage is too low, which also indicates that it needs to be charged.
- Since the decoder board lacks a protection circuit for lithium batteries, it is recommended to use this module with a Lipo charging board.
- Pay attention to electrostatic protection. As the Bluetooth chip is very sensitive to static electricity, you need to discharge the static electricity on your hand to avoid damaging the chip when touching 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 avoid placing this board near metal objects.
