Questions

How big is the PCB Design PCB?

It measures 40 × 100 mm and has 2 copper layers, 1.6 mm thick.

What parts does the PCB Design use?

30 parts, built around the ATMEGA328P-PU and L7805. 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 PCB Design KiCad files?

From the RNA-IITPatna/Flight-Controller repository on GitHub, at the commit this page was made from: the board is Version 1.0/PCB-Design/KiCAD Files/PCB-Design.kicad_pcb and its schematic Version 1.0/PCB-Design/KiCAD Files/PCB-Design.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the PCB Design design in my own project?

Its repository states no licence, so its author keeps all rights: ask RNA-IITPatna before reusing the design.
