Questions
What parts does the Rfm to usb use?
19 parts, built around the STM32F103C8T6 and XC6206-3.3V. 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 Rfm to usb KiCad files?
From the dltech/rfm69_usb repository on GitHub, at the commit this page was made from: the board is schematic/rfm_to_usb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rfm to usb design in my own project?
Its repository states no licence, so its author keeps all rights: ask dltech before reusing the design.
