Questions
How big is the RF proj PCB?
It measures 76.2 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RF proj use?
117 parts, built around the ATMEGA328P-AU, TLV2464CD, 74AC74M and 74CBTLV3253D. 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 RF proj KiCad files?
From the mgw93/RF-proj repository on GitHub, at the commit this page was made from: the board is rf_proj.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the RF proj design in my own project?
Its repository states no licence, so its author keeps all rights: ask mgw93 before reusing the design.
