Questions
How big is the Capamesure PCB?
It measures 75 × 48 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Capamesure use?
61 parts, built around the MMBT3904 and MMBT3906. 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 Capamesure KiCad files?
From the Londrius/Capamesure repository on GitHub, at the commit this page was made from: the board is Capamesure/Capamesure.kicad_pcb and its schematic Capamesure/Capamesure.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Capamesure design in my own project?
Its repository states no licence, so its author keeps all rights: ask Londrius before reusing the design.
