Questions
How big is the Georesistance PCB PCB?
It measures 82.3 × 76.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Georesistance PCB use?
90 parts, built around the ADS1115IDGS, LM2776DBV, RS8552 and RS8554XQ. 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 Georesistance PCB KiCad files?
From the zemonkey/Georesistance-Final-Project repository on GitHub, at the commit this page was made from: the board is Georesistance PCB/Georesistance PCB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Georesistance PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask zemonkey before reusing the design.
