About the Adapter spdif PCB

Adapter spdif is an open source PCB design by FOSDEM, published on GitHub. It is a 2-layer board measuring 44 × 33 mm, with 11 components from 10 distinct parts.

Other key parts include the 74HCU04D. By type, the board carries 5 resistors, 3 capacitors, 2 connectors and 1 IC.

It belongs with the audio designs in this gallery.

From the project

A full build needs several parts. All of these should be easily reproducible, while for the ones where we rely on an external manufacturer, we made sure to have ample spares.

A full build needs several parts. All of these should be easily reproducible, while for the ones where we rely on an external manufacturer, we made sure to have ample spares.

You will need one of each item, except when stated otherwise.

The case is an off-the-shelf widely available 1U case, made by Gainta.

We only use the actual enclosure. All other bits can be discarded.
