Questions
How big is the RFUtilityKnife PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RFUtilityKnife use?
272 parts, built around the LM317MDT, NE555, 2SC3356 and MMBT5551. 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 RFUtilityKnife KiCad files?
From the profdc9/RFUtilityKnife repository on GitHub, at the commit this page was made from: the board is RFUtilityKnife.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the RFUtilityKnife design in my own project?
Its repository states no licence, so its author keeps all rights: ask profdc9 before reusing the design.
