Matrix router

4 stereo inputs to 4 outputs, tileable, first 4-layer board

Overview

This is a project I worked on the summer before going to stanford. It routes 4 stereo audio channels to 4 outputs, and is tileable.

Say we label columns like 1 2 3 4 and rows like A B C D. Then pushing A1 routes input A to output 1.

Push a button, route that row’s input to that column’s output

Nati Grinkrug made the sweet enclosure model and render back in the day before vibecad. This was my first 4 layer pcb. Quite a complicated mech.

Board files: front · back (PDF).
