Questions
How big is the Relay ctrl lab PCB?
It measures 221 × 74.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Relay ctrl lab use?
63 parts. 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 Relay ctrl lab KiCad files?
From the ograsdijk/CeNTREX-pcb repository on GitHub, at the commit this page was made from: the board is interlock/relay_ctrl_lab/rev 3.0/relay_ctrl_lab.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Relay ctrl lab design in my own project?
Its repository states no licence, so its author keeps all rights: ask ograsdijk before reusing the design.
