Questions
How big is the Panel PCB?
It measures 110 × 121 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Panel use?
116 parts, built around the ATMEGA328PB-AU, FT231XS-R, L78M05ABDT-TR and 2N7002,215. 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 Telekomak/FiresportTimer repository on GitHub, at the commit this page was made from: the board is PCB/Production/panel.kicad_pcb and its schematic PCB/FT_Hall/FT_Hall.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 Telekomak before reusing the design.
