Questions

How big is the FlapFlap PCB?

It measures 65 × 44 mm and has 2 copper layers, 1.6 mm thick.

What parts does the FlapFlap use?

21 parts, built around the T835-600B-TR and MOC3043M. 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 FlapFlap KiCad files?

From the ehajo/FlapFlap repository on GitHub, at the commit this page was made from: the board is Platine/KiCad/flapflap/flapflap.kicad_pcb and its schematic Platine/KiCad/flapflap/flapflap.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the FlapFlap design in my own project?

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