Questions
How big is the SimplerFlightV2 PCB?
It measures 93.8 × 73.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SimplerFlightV2 use?
114 parts, built around the TPS56A37RPAR, BMP581, MX25V4006EM1I-13G and DM3CS-SF. 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 SimplerFlightV2 KiCad files?
From the elenajusto/SimplerFlightV2 repository on GitHub, at the commit this page was made from: the board is SimplerFlight_v2.kicad_pcb and its schematic SimplerFlight_v2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SimplerFlightV2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask elenajusto before reusing the design.
