UART / Button Control Bluetooth Phone Call SMD MP3 Music Player Module
This is Bluetooth sound module with the function of intelligent wireless audio data transmission and MP3 playing. This is a stereo wireless transmission scheme with low cost and high efficiency£¬ and with the advantages of high integration£¬ small size£¬ low power consumption and fast transmission speed. Just a few components are added on the peripheral module and then high-quality stereo audio wireless reception can be achieved. The module itself is adopted with free driving mode. Customers only need to apply the module to application products£¬ then it can realize the fast wireless music transmission. The module itself has three main features: MP3 function (can plug SD card£¬ U disk)£¬ mobile phone Bluetooth communication£¬ and UART serial port control. - Standard UART communication interface£¬ default baud rate 9600; flexibly realizing the specified address play£¬ specified file-name play£¬ file play in specified folder£¬ volume series£¬ the previous/ next£¬ stop play£¬ combination play£¬ memory switching and play selection mode; no play by default with power on. - Serial communication format: 8N1 - Working voltage: 3V~5.3V - Interface logic voltage: 3.3V - With standard key function£¬ play/ stop£¬ the previous£¬ the next£¬ volume up£¬ volume down£¬ mode switch and so on. - Support three storage modes: SPI-FLASH£¬ SD card£¬ U disk. SPI-FLASH is a fixed sound source area and users cannot change that. - USB interface makes automatic switching function between the master (USB HID) and slave (USB card reader). - Support FAT16£¬ FAT32 file system£¬ MP3 and WAV£¨PCM£¬ IMA - ADPCM) format audio files.
