Questions
How big is the Sheet PCB?
It measures 111 × 97.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sheet use?
88 parts, built around the ATTINY1616-MN, MCP2562-E/MFVAO, ADS7830IPW and AP2112K-3.3. 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 Sheet KiCad files?
From the shepai/TacSheet repository on GitHub, at the commit this page was made from: the board is PCB/Sheet/Sheet.kicad_pcb and its schematic PCB/Old/Logic_approach.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sheet design in my own project?
Its repository states no licence, so its author keeps all rights: ask shepai before reusing the design.
