This plug-and-play stereo amplifier is based on a highly integrated single chip USB audio processor chip and is ideal for use in kiosks, embedded Linux or single board computer applications for Raspberry Pi. The amplifier simply appears as a standard USB speaker to the operating system and is therefore compatible with built-in drivers already available in any modern operating system including Windows, Linux and OS X. Furthermore, it is USB bus powered and does not require any external power source to operate and offers music power of up to 1W per channel.The unit offers both Left and Right RCA jacks for the output as well as a 3.5mm stereo jack for easy connection to any audio source.
