Questions
How big is the FireFlyV2 PCB?
It measures 67.7 × 10.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the FireFlyV2 use?
75 parts, built around the ESP32-C3FH4, RP2040, W25Q32JVUUIQ and AMS1117-3.3. 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 FireFlyV2 KiCad files?
From the kylaro/firefly-led-controller repository on GitHub, at the commit this page was made from: the board is FireFlyV2/FireFlyV2.kicad_pcb and its schematic FireFlyV0/FireflyV0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FireFlyV2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask kylaro before reusing the design.
