Questions
How big is the MP1 PCB?
It measures 15.5 × 15.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MP1 use?
15 parts, built around the MCP6021-E/P. 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 MP1 KiCad files?
From the TinyTinfoil/MP1-Eclectronics repository on GitHub, at the commit this page was made from: the board is MP1.kicad_pcb and its schematic MP1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MP1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask TinyTinfoil before reusing the design.
