Questions
How big is the Tip Etcher PCB?
It measures 87.6 × 63.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tip Etcher use?
89 parts, built around the RP2350A, TMC2208SILENTSTEPSTICK, TPS54331DDA and LM1117DT-3.3. 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 Tip Etcher KiCad files?
From the KN-NaMi/Tip-Etcher repository on GitHub, at the commit this page was made from: the board is electronics/mainboard/mainboard.kicad_pcb and its schematic electronics/mainboard/mainboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tip Etcher design in my own project?
Its repository states no licence, so its author keeps all rights: ask KN-NaMi before reusing the design.
