Questions
How big is the SAFMC FC PCB?
It measures 85 × 56 mm and has 4 copper layers, 1.6 mm thick.
What parts does the SAFMC FC use?
125 parts, built around the DWM1000, BMP280, AMS1117-3.3 and BMI088. 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 SAFMC FC KiCad files?
From the radityankn/SAFMC_FC repository on GitHub, at the commit this page was made from: the board is SAFMC_FC/SAFMC_FC.kicad_pcb and its schematic SAFMC_FC/Ports_LED_Buzzer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SAFMC FC design in my own project?
Its repository states no licence, so its author keeps all rights: ask radityankn before reusing the design.
