From the project

A lid for the Kimchi SBC that provides: Stereo audio ouptut/input, mic in, and headphone output.

This directory contains the KiCad hardware files for the SGTL5000-based audio PCB variant of the Kimchi HiFi Lid project.

The board is an audio codec / interface PCB intended to mate with the main Kimchi hardware through high-density board-to-board connectors. It includes the audio codec, clocking, analog I/O connectors, EEPROM, local power filtering, and supporting passives required for the SGTL audio path.
