As shown below BT5.0 Audio PRO Mini Bluetooth 5.0 MP3 Deer Board Audio Receiver MP3 Lossless Player Wireless Stereo Music Amplifier Module Lithium battery charging Incoming call BT5.0 Audio PRO continues the excellent basic functions of M28 (-distance transmission, Bluetooth 5.0 backward compatible, lossless sound quality, etc.), and adds more user-friendly performance, as follows: Charge while putting: This product has a circuit of charging and discharging, which can directly charge the battery through the USB power supply, and Bluetooth can continue to work normally during the charging process, and truly realize the function of charging and discharging. Solve the pain point that some products can not be used during the charging process. When powered by USB alone: The red light flashes, indicating that the power supply is normal. When powered by a separate battery: The yellow light is always on, indicating that the battery power supply is normal; the yellow light flashes, indicating that the battery is low. When the USB and battery are connected at the same time: The red light flashes to indicate that the battery is charging; the red light always indicates that the battery is fully charged. (Note that if the USB input is suddenly disconnected during the charging and discharging process, there will be a few seconds of interruption due to the charge and discharge mode switching at this time, after which Bluetooth will automatically restart, automatically connect and maintain the previous playback state) Incoming voice call function: After the Bluetooth is connected, turn on the call audio mode in the Bluetooth settings. If the phone calls, you can answer or hang up the phone through the PLAY/STOP on. You can choose to send from the microphone of the headset (provided that the headset has a call function, which is a 4-segment type) or from the onboard microphone (default), see the function description for details. When the computer sound card is used: Tin the pads in the two boxes corresponding to the Sound Card on the back of the module, and then connect it to the USB interface of the computer through the USB cable, which can be used as a sound card. That is, the sound played by the computer is output through the audio interface of the module. See function description for details. (Not enabled by default) Product Size: Product Features: Introduction without remote control: Operation instructions After switching on the power supply, the blue indicator flashes and enters the Bluetooth mode; after broadcasting the "prompt sound", it enters the matching mode and waits for matching; after broadcasting the "prompt sound", the mobile Bluetooth searches for "XY-WRBT" (the name of the power amplifier board device), clicks on the "XY-WRBT" connection, and plays the "prompt sound" after the connection is successful, and when the indicator light is , the mobile music can be played. When playing music, the indicator light flickers slowly; after Bluetooth disconnects, the amplifier board prepares for the next pairing, and plays the "prompt tone" and enters the pairing mode to wait for the pairing. Cautions for Power Supply with 3.7V Lithium Battery 1. When powered by batteries, the battery voltage is less than 3.3V deer board automatically shuts down, and the contacts are switched on/off for 2 seconds after re-energizing or full charging. 2. When using batteries to supply power, if the voltage of batteries is too low, there may be "nourishing" noise. In this case, the batteries need to be charged. 3. Because there is no charge protection circuit for lithium batteries on deer board, it is recommended to use lithium batteries with protection board. 4. If your rechargeable battery supports Micro USB charging directly, you can use Micro USB charging directly to the battery. Product Instructions with remote control:
