Questions
How big is the EW281C FC PCB?
It measures 29.5 × 29.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the EW281C FC use?
82 parts, built around the BMP280, W25Q128JVSIQ, LP2985-33DBV and MP4462DN. 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 EW281C FC KiCad files?
From the jpwolfe9912/EW281C_FC repository on GitHub, at the commit this page was made from: the board is EW281C_FC.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the EW281C FC design in my own project?
Its repository states no licence, so its author keeps all rights: ask jpwolfe9912 before reusing the design.
