Questions
How big is the Panel PCB?
It measures 204 × 184 mm and has 4 copper layers, 1.68 mm thick.
What parts does the Panel use?
2,711 parts, built around the CMT2219A-EQR, ST25R3916B-AQWT, XYC-PT0805BC-L4-D and 74HC595BQ. 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 ItsShadowCone/tmfl repository on GitHub, at the commit this page was made from: the board is hardware/full-poc/panel.kicad_pcb and its schematic hardware/frontcover/frontcover.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 states no licence, so its author keeps all rights: ask ItsShadowCone before reusing the design.
