Serial Controlled Mp3 Module
This MP3 Module is one of ElecFreaks self-developed modules inspired by the JQ6500-24SS MP3 chipset. It supports SD cards for FAT16, FAT32 file systems and SPI Flash updates via PC. Using some very simple serial commands to control music playback, it's easy to operate and great for use with external controllers. Additionally, with an external headphone (PH) and an external speaker (SP), the MP3 Module provides more interfaces and utility.
