Raspberry Pi IQAudio DAC+

The IQAudio Pi-DAC+ is a high-quality audio HAT for the Raspberry Pi, delivering full-HD 24-bit/192 kHz audio output via the Pi's I2S digital audio bus. It provides significantly better sound quality and lower CPU usage compared to USB audio solutions, with hardware volume control accessible through standard ALSA Linux audio APIs.

Designed to the official Raspberry Pi HAT specification with auto-configure EEPROM, the board includes RCA phono connectors with integrated mounting holes, camera and display ribbon cable cut-outs, and aligned mounting points for a rigid, long-term connection.
