Questions
How big is the Kiss masterboard PCB?
It measures 187 × 152 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Kiss masterboard use?
163 parts, built around the ICE40UP5K-SG48I, TPS53819ARGT, TPS54327DRC and SN74LVC8T245PW. 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 Kiss masterboard KiCad files?
From the squarewavedot/ledcubeelectronics repository on GitHub, at the commit this page was made from: the board is kiss-masterboard/masterboard_v0.2/kiss-masterboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kiss masterboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask squarewavedot before reusing the design.
