Questions
How big is the Rdf kicad PCB?
It measures 191.8 × 123 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Rdf kicad use?
265 parts, built around the ADL5380ACPZ-R7, BSW6440, QPL9547 and ESP32-S3-DEVKITC-1-N8. 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 Rdf kicad KiCad files?
From the megmem044/Portfolio repository on GitHub, at the commit this page was made from: the board is rf_direction_finder/hardware/rdf_kicad/rdf_kicad.kicad_pcb and its schematic rf_direction_finder/hardware/rdf_kicad/digital_section.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rdf kicad design in my own project?
Its repository states no licence, so its author keeps all rights: ask megmem044 before reusing the design.
