Questions
How big is the Fab PCB?
It measures 272.7 × 159.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Fab use?
170 parts, built around the STM32F103CBT6, ENC28J60-I/SP, MCP6002-I/P and TS2940CZ33 C0G. 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 Fab KiCad files?
From the horazont/hint repository on GitHub, at the commit this page was made from: the board is sensor-node-2.0/fab.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fab design in my own project?
Its repository states no licence, so its author keeps all rights: ask horazont before reusing the design.
