Questions

How big is the GUSar PCB?

It measures 167.6 × 106.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the GUSar use?

149 parts, built around the TDA1308A, TL082, 74AHCT373D and 74LS32SC. 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 GUSar KiCad files?

From the tuutuum/guspnp repository on GitHub, at the commit this page was made from: the board is GUSar.kicad_pcb and its schematic GUSar.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the GUSar design in my own project?

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