FOSDEM Video Repository
This repository is meant to keep track of the development for video at FOSDEM.
The hardware subfolder contains the overview and information describing the architecture and all things hardware-related of the FOSDEM video setup.
The software subfolder contains the source of scripts and other bits and pieces.
The instructions subfolder contains both source files and generated PDF files with instructions and reference pictures for use during FOSDEM itself.
The infrastructure repository contains the ansible recipes to deploy the video infrastructure.

Questions
How big is the Switch board PCB?
It measures 84 × 83 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Switch board use?
109 parts, built around the RTL8367S-CG, TPS562231DRL, W25Q32JVSSIQ and 24LC64(LX). The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Switch board KiCad files?
From the FOSDEM/video repository on GitHub, at the commit this page was made from: the board is hardware/pcbs/switch_board/switch_board.kicad_pcb and its schematic hardware/pcbs/audio_board/adc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Switch board design in my own project?
Its repository states no licence, so its author keeps all rights: ask FOSDEM before reusing the design.
