An open-hardware and -firmware project that implements a USB-input fully-digital class-D audio amplifier.

All processing is done on FPGA, including the USB-physical, USB-SIE, HID interface, clock-recovery, bus voltage regulation, noise-shaping and PWM output.

A Microchip PIC based remote control is also included. The remote maps to the media buttons of the USB HID interface. The volume control, next track, previous track, stop and play/pause functions are supported.

Features

  • 200 W (RMS) per channel output power
  • USB Audio 1.0 input
  • Uses the generic Windows drivers
  • RF remote control
