Questions

How big is the Gen PCB?

It measures 155.8 × 76.6 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Gen use?

57 parts, built around the IRM-90-24, SMBJ6.0A, B340 and SMBJ28A. 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 Gen KiCad files?

From the ArnavMK/WaveForge repository on GitHub, at the commit this page was made from: the board is Hardware/Gen/gen.kicad_pcb and its schematic Hardware/Gen/gen.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Gen design in my own project?

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