N9200B is a MP3 chip that provides serial port,which perfectly integrates MP3 and WMV hard decoder chips.

It includes the N9200A and N9200B Music MP3modules,and the software supports TF driver, supports the computer to update the content of SPI-flash directly, and supports the FAT16 and FAT32 file systems.

Through a simple UART serial command or a first-line serial port instruction to play the specified music, and how to play music and other functions, without the tedious underlying operation, good sound quality, easy to use, stable and reliable is the biggest feature of this product.

In addition, the chip is also a product of deep customization, which is a low-cost solution for fixed voice playback.
