Questions
How big is the FireFly PCB?
It measures 109.6 × 72 mm and has 2 copper layers, 1.5 mm thick.
What parts does the FireFly use?
80 parts, built around the CC1101RGP, BAT54WS, BLM15AG102SN1 and MMBT2222. 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 FireFly KiCad files?
From the Kreyl/Firefly_hw repository on GitHub, at the commit this page was made from: the board is PCB/FireFly.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the FireFly design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kreyl before reusing the design.
