Questions
How big is the RelaisAddierer PCB?
It measures 290.1 × 175 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RelaisAddierer use?
262 parts, built around the TCA9534PW, 1N4148WT, BC847 and DMP3099L. 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 RelaisAddierer KiCad files?
From the apxco/Kicad repository on GitHub, at the commit this page was made from: the board is Useless_Relais_Adder/RelaisAddierer/RelaisAddierer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the RelaisAddierer design in my own project?
Its repository states no licence, so its author keeps all rights: ask apxco before reusing the design.
