Questions

How big is the Right PCB?

It measures 207.2 × 149.1 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Right use?

244 parts, built around the SN74LV1T125DBV, BQ24075RGT and USBLC6-2SC6. 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 Right KiCad files?

From the sanoojes/SplitKeeb repository on GitHub, at the commit this page was made from: the board is pcb/Right/Right.kicad_pcb and its schematic pcb/Combined/Combined.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Right design in my own project?

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