Questions
How big is the Candle PCB?
It measures 13.8 × 74.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Candle use?
58 parts, built around the CC1101RGP, MMA8452QT, BLM15AG102SN1 and BAT54WS. 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 Candle KiCad files?
From the Kreyl/Candle repository on GitHub, at the commit this page was made from: the board is Candle_hw/Candle.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Candle design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kreyl before reusing the design.
