BT5.0 Audio PRO Mini Bluetooth 5.0 MP3 Decoder 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 (long-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 button. You can choose to send from the microphone of the original 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:

Rotating LED electronic clock
Features: The electronic clock adopts the principle of digital tube display design, adopts the design of plug-in components, and has high success rate. Contains six Time animation, effective display of time and various functions. LED flashing light includes four offline animation display modes, lighting effects The fruit is very decorative, bringing a good aesthetic to the home and table. The electronic clock is alternately displayed with time and temperature. Precise and with power-down memory travel time function. With an alarm clock function, it can be turned off. With light control function, according to the environment Adjust the brightness.
Circuit principle:
Using single-chip microcomputer as the main control, use DS1302 travel time chip to provide accurate travel time clock source, combined with digital tube And LED lights show specific time values. Combined with the temperature light intensity detecting element, it can achieve the brightness adjustment and temperature check attached. Test function. The control button of the single chip is combined with the necessary key input adjustment function, and the clock sound is processed by the single chip and then beep.
 
Common problem:
1. The welding sequence is wrong. It is recommended to solder the LED lamp first, then solder the back component, solder the digital tube, and finally insert the chip. 2. LED lights pay attention to the positive and negative poles, long legs and positive poles. 3. The chip notch and the base notch must be consistent with the notch identified on the board. 4. Buzzer pay attention to positive and negative poles, long foot positive pole, resistance resistance value to follow Consistent on the logo. 5. The triode should be inserted in the same shape as the board. 6. The digital tube pays attention to the direction, and the decimal point is below. 7. Power supply pay attention to the positive and negative poles, the power supply DC voltage is 5V. 8. Check for solder shorts and solder joints. This phenomenon is common. 9. If the display is abnormal or the time is not gone, remove the DS1302 and buttons. Battery, then plug in the DS1302, do not plug in the battery, and then power on, Put the battery on after normal. 10. If the individual lights are not lit, check the solder shorts of the unlit lights and Soldering, check it, and change the light if it is not lit. 11. If the four digital tubes have the same segment code that is always on and highlighted, Some LEDs are also always on because of an electrostatic breakdown of an LED. a digital tube that causes a single-chip pin to share with this lamp.
