Questions
How big is the SimpleTXtx PCB?
It measures 30.5 × 33 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SimpleTXtx use?
13 parts, built around the 2SC1815 and RCJ-044. 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 SimpleTXtx KiCad files?
From the zosko/simpleTVtx repository on GitHub, at the commit this page was made from: the board is KiCad/simpleTXtx.kicad_pcb and its schematic KiCad/simpleTXtx.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SimpleTXtx design in my own project?
Its repository states no licence, so its author keeps all rights: ask zosko before reusing the design.
