About the Cd changer emulator PCB

Cd changer emulator is an open source PCB design by akreager, published on GitHub under the MIT license. It is a 2-layer board measuring 22 × 80 mm, with 5 components from 3 distinct parts.

It belongs with the audio, dev boards & breakouts and retro computing designs in this gallery.

From the project

Raspberry Pi CD changer emulator for 1990s Kenwood car stereos. Reverse-engineers the 13-pin DIN serial protocol and replaces the changer with a Pi HAT featuring ATtiny1616, PCM5102A DAC, and automotive power management.

This KiCad project implements a passive, pass-through breakout board for the Kenwood KRC-3006 head unit's 13-pin mini DIN connector. The board provides:

- Signal routing between the KRC-3006 and connected CD autochanger. - Accessible test points for bus signal analysis and protocol reverse engineering. - Isolated audio path with independent head unit and changer TRS audio jack connectors.
