MP3 Player Module
MP3 Module is one of Elecfreaks self-developed modules inspired by JQ6500-24SS MP3 chipset of Jiaqiang Electronics. It supports SD cards for FAT16, FAT32 file systems and SPI Flash updates via PC. Via some very simple serial commands to control music playback, it owns the characteristics of easy operation and stable performance. Additionally, with an external headphone (PH) and an external speaker (SP), the MP3 Module provides more interfaces and utility.
