Questions
How big is the Pico router backup PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pico router backup use?
98 parts, built around the 2SK4017(Q). 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 Pico router backup KiCad files?
From the Dudestin/tinyEtherDeveloper repository on GitHub, at the commit this page was made from: the board is PCB_project/pico_router/pico_router_backup.kicad_pcb and its schematic PCB_project/pico_router/pico_router.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pico router backup design in my own project?
Its repository states no licence, so its author keeps all rights: ask Dudestin before reusing the design.
