The VMUSIC3 is an USB host and MP3/WMA player Vinculum-II Development Module. The default firmware of the VMUSIC3 supports audio playback and UART or SPI communication interfaces for integration into the target product. VMUSIC3 can be used to read MP3 and other audio format files from a USB flash disk, process the data and output the stereo audio through the line-out header and headphone jack. The VMUSIC3 is a drop in replacement for the VMusic2 for the majority of VMusic2 applications. VMUSIC3 uses firmware called V2MSC which is similar to V2DAP (used in VDrive3) with an additional module for controlling MP3 playback. However for a small number of applications that use SPI, differences exists between VMusic firmware and V2MSC firmware which would require some changes to be made to the application software.
