Questions
How big is the 80mrx PCB?
It measures 40 × 29.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 80mrx use?
46 parts, built around the BC847. 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 80mrx KiCad files?
From the Harry-Zhang121/notes repository on GitHub, at the commit this page was made from: the board is Training_lab/kicad/80mrx/80mrx.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 80mrx design in my own project?
Its repository states no licence, so its author keeps all rights: ask Harry-Zhang121 before reusing the design.
