Questions
How big is the Rc plane v1.0 PCB?
It measures 47 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rc plane v1.0 use?
63 parts, built around the E22-900M22S, AP2112K-3.3 and MCP73871-2CCI/ML. 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 Rc plane v1.0 KiCad files?
From the koppanybme/rc-plane repository on GitHub, at the commit this page was made from: the board is kicad/rc_plane_v1.0/rc_plane_v1.0.kicad_pcb and its schematic kicad/rc_plane_v1.0/.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rc plane v1.0 design in my own project?
Its repository states no licence, so its author keeps all rights: ask koppanybme before reusing the design.
