JQ6500 Serial MP3 Voice Module

JQ6500 Voice Sound Module USB DIP16 TTL UART MP3 Breakout Replace One to 5 Way MP3 Voice 3.2-5V 20mA 16MIntroduction JQ6500 is an MP3 chip that provides serialization, which perfectly integrates the hard decoding of MP3 and WMV. At the same time, the software supports TF card driver, supports computer to directly update the content of spi flash, supports FAT16, FAT32 file system. The function of playing the specified music and how to play the music can be completed through a simple serial port command, without the tedious underlying operation, easy to use, stable and reliable are the biggest features of this product. In addition, the chip is also a deeply customized product, a low-cost solution specially developed for the fixed voice playback field. Features 1. Support sampling rate (KHz): 8/11.025/12/16/22.05/24/32/44.1/48 2. 24-bit DAC output, dynamic range supports 90dB, signal-to-noise ratio supports 85dB 3. Fully support FAT16, FAT32 file system, maximum support 32G 4. TF card, support 32G U disk, 64M byte NORFLASH4, multiple control modes, parallel port control mode, serial port mode, AD button control mode 5. Broadcast language insertion function, you can pause the background music that is playing 7. 30-level volume adjustable, 10-level EQ adjustable 8. You can plug in spi flash, and connect to the computer to display the drive letter of spi flash to update the content; 9. It can be controlled to play the specified music through the serial port of the microcontroller; 10. In the button mode, the playback mode can be selected: interruptible, non-interruptable, single loop, large loop;Interruptible: In the process of playing, pressing the button will interrupt the current state to execute a new one; Uninterrupted: that is, in the process of playing, pressing any button is invalid until the current track is played; Application 1. Voice broadcast of car navigation 2. Voice prompts for road transport inspections and toll stations; 3. Voice prompts for safety inspection at railway stations and bus stations; 4. Voice prompts for electricity, communication and financial business halls; 5. Voice prompts for vehicle entry and exit channel verification; 6. ** Frontier inspection channel voice prompt; 7.
