Questions
How big is the AMN TopPcb PCB?
It measures 93 × 93 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AMN TopPcb use?
31 parts, built around the ATTINY3224-SSU. 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 AMN TopPcb KiCad files?
From the hschack/ANM_TOP_PCB repository on GitHub, at the commit this page was made from: the board is AMN_TopPcb/AMN_TopPcb.kicad_pcb and its schematic AMN_TopPcb/AMN_TopPcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AMN TopPcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask hschack before reusing the design.
