Questions

How big is the CC1101 RPi PCB?

It measures 85 × 56 mm and has 2 copper layers, 1.6 mm thick.

What parts does the CC1101 RPi use?

150 parts, built around the CC1101RGP, PCF8574T and M2.5. 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 CC1101 RPi KiCad files?

From the eydam-prototyping/cc1101 repository on GitHub, at the commit this page was made from: the board is KiCad/CC1101_RPi/CC1101_RPi.kicad_pcb and its schematic KiCad/CC1101_RPi/CC1101_RPi.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the CC1101 RPi design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
