Questions

How big is the Atverter Fly PCB?

It measures 3.7 × 3.6 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Atverter Fly use?

60 parts, built around the ATMEGA328P-PU, 74HC02 and IRF540N. 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 Atverter Fly KiCad files?

From the WillSoar21/Flyback_AtverterE repository on GitHub, at the commit this page was made from: the board is Flyback Designs/Flyback_PCBs/r4 Atverter_Fly/Atverter_Fly.kicad_pcb and its schematic Flyback Designs/Flyback_PCBs/r1 Atverter_Fly/Atverter_Fly.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Atverter Fly design in my own project?

Its repository states no licence, so its author keeps all rights: ask WillSoar21 before reusing the design.
