Description
Product Description
QJ007 is an MP3 chip with a serial port for MP3 and MAV decoding which supports USB / SD/TF FLASH drive, FAT16, and FAT32 file system. We can playback the specified music with simple serial command, and simply switch audio playback mode, no need for the cumbersome bottom operation. Besides, it can directly play USB / SD/TF FLASH internal songs or download, easy and convenient.
Its stability and simple operation are the biggest advantages of this chip, is widely used for fixed voice playback field development at a low cost. It would be your optimal choice for the engineer working with various audio files.
