Questions
How big is the Ad8342evb PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Ad8342evb use?
99 parts, built around the OPA2320 and TP1. 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 Ad8342evb KiCad files?
From the catkira/ad8342evb repository on GitHub, at the commit this page was made from: the board is ad8342evb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ad8342evb design in my own project?
Its repository states no licence, so its author keeps all rights: ask catkira before reusing the design.
