Questions
How big is the Firefly5 PCB?
It measures 16 × 63 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Firefly5 use?
53 parts, built around the STM32F030C8T6, CC2500RGP and TEMT7000X01. 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 Firefly5 KiCad files?
From the Kreyl/Fireflies repository on GitHub, at the commit this page was made from: the board is Firefly5/Firefly5_hw/Firefly5.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Firefly5 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kreyl before reusing the design.
