Questions

How big is the Kasm pcb rev2 PCB?

It measures 121 × 70.6 mm and has 6 copper layers, 1.6 mm thick.

What parts does the Kasm pcb rev2 use?

268 parts, built around the 74LVC2G07GV and STSPIN240. 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 Kasm pcb rev2 KiCad files?

From the gabeak2/KASM_ACTUATOR_PCB_REV2 repository on GitHub, at the commit this page was made from: the board is kasm_pcb_rev2.kicad_pcb and its schematic HRTIM_CHA1_HRTIM_CHA2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Kasm pcb rev2 design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
