In this repo you will find
- Hardware files (in Kicad)
- Firmware files (C++ mainly) (Haven't started this yet)
- Software files (Python) (Haven't started this yet, ideally I'd like a nice GUI to talk to the firmware to configure SwitchBlox)

Questions
How big is the SwitchBlox PCB?
It measures 44.5 × 44.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SwitchBlox use?
86 parts, built around the KSZ8895MQXCA, HX1344NL and PT61017PEL. 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 SwitchBlox KiCad files?
From the msadowski/SwitchBlox repository on GitHub, at the commit this page was made from: the board is Hardware/Release Design Files/Source Kicad Files/SwitchBlox.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SwitchBlox design in my own project?
Its repository states no licence, so its author keeps all rights: ask msadowski before reusing the design.
