Questions
How big is the Panel PCB?
It measures 227.8 × 132.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Panel use?
556 parts, built around the SLG47004V, ESP32-S3-WROOM-1-N8, SLG88103V and ALT021-10E. 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 Panel KiCad files?
From the YDrip/ydrip-pcb repository on GitHub, at the commit this page was made from: the board is panel.kicad_pcb and its schematic sensors.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Panel design in my own project?
Its repository publishes it under the CERN-OHL-W-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
