Questions
What parts does the DexcomReader use?
28 parts, built around the CC2511F32RSP and BQ21040DBV. 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 DexcomReader KiCad files?
From the mrwillem/PCBs repository on GitHub, at the commit this page was made from: the board is DexcomReader/DexcomReader.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the DexcomReader design in my own project?
Its repository states no licence, so its author keeps all rights: ask mrwillem before reusing the design.
