Questions

How big is the Hashat PCB?

It measures 65 × 56.5 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Hashat use?

109 parts, built around the SN74LVC1T45DBVRE4, DS4432U+, LN1134A182MR-G and SGM2036-ADJYN5G/TR. 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 Hashat KiCad files?

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

Can I use the Hashat design in my own project?

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