Questions
How big is the Mostlylevel before reroute PCB?
It measures 50 × 86 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mostlylevel before reroute use?
31 parts, built around the ESP32-S3-WROOM-1-N16R8, ME6217C33M5G, USBLC6-2SC6 and AO3400A. 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 Mostlylevel before reroute KiCad files?
From the roman-mueller-ch/MostlyLevel repository on GitHub, at the commit this page was made from: the board is hardware/routing/mostlylevel_before_reroute.kicad_pcb and its schematic hardware/mostlylevel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mostlylevel before reroute design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
