1 Remote USB-SD Mp3 FM Radio Player Module With LED Display -A 1 Overview This high quality MP3 module is an untiversal and compact embedded module in credit-card size for playing compressed audio data (MP3) and WMA format files. The module was designed for use in embedded systems and for integration in customer specific environment. It is a versatile audio module for working in rough industrial applications.the module has a Compact Flash (CF) card slot for using with CF cards type I or II.Controlling the module could be done either by button or remote control. The internal firmware of the module could be adapted to the customer needs. This pre-assembled PCB contains the electronics needed to play MP3 files from hard drives, CDROMs or compact flash cards. Just plug in a spare drive & power supply, put it in a project box, hook it to an amp, and you have a track MP3 player suitable for the car or home. Alternatively, use our compact flash adaptor with a 1GB+ card for a portable low-power solution. The player provides a line-out signal, suitable for connecting to the auxiliary input of an amplifier or head-end unit. A high-resolution 24-bit DAC and dedicated decoder DSP produce a quality sound even at low bitrates. The player also has some additional features, such as support for FAT16 or FAT32 file systems, ID3 tag support, and the ability to 'learn' different VCR and CD remote controls. This module has multimedia MP3 audio decode board, which highly integrated single-chip. And add extra signal switch, USB / SD switch, digital display. The chief advantage are fast user-friendly and convenient. What s more, not only enrich programs with radio feature, but also enhance the U disk and SD compatibility. This module is widely used in home music centers, car stereo and computer multimedia stereo, professional audio active, IPOD audio, AV amplifier, massage chairs, electronic gifts, electronic toys and so on. The module has been in mass production, stable performance. And we offer a wide selection of this panels.
