Questions

How big is the Controller PCB?

It measures 64.8 × 76.2 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Controller use?

73 parts, built around the UCC27523D, 74HC08D, 74HC14 and 74HC74D. 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 Controller KiCad files?

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

Can I use the Controller design in my own project?

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