Questions
How big is the LL2FRsky PCB?
It measures 31.1 × 33 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LL2FRsky use?
30 parts, built around the ATMEGA88PA-AU, LM1117-3.3 and BC847. 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 LL2FRsky KiCad files?
From the lfischer85/LinkLive2SPort repository on GitHub, at the commit this page was made from: the board is LL2FRsky/LL2FRsky.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LL2FRsky design in my own project?
Its repository states no licence, so its author keeps all rights: ask lfischer85 before reusing the design.
