# FoxDAC - a USB / TOSLINK Audio DAC

![DAC PCB](hardware/sidebyside.png)

## Features

* Built around the Raspberry Pi Pico, running @ 192MHz (48/96kHz) or ~176.6MHz (44.1kHz)

* Up to 16 bit / 96kHz audio support over USB

* LVGL-based UI with an SSD1306 OLED display and rotary encoder

* Cirrus WM8805 S/PDIF transceiver for TOSLINK reception as I2S master

* 3x TORX147 TOSLINK optical inputs

* USB audio gets sent as S/PDIF to the WM8805 for clock de-jitter

* TI TPA6130 headphone amplifier with I2C volume control

* ESS9023 DAC powered from TI LP2985 LDO

* Optional biquad equalizer running on both cores
