Questions
How big is the ProMicro BOOST PCB?
It measures 17.8 × 27.9 mm and has 4 copper layers, 0.8 mm thick.
What parts does the ProMicro BOOST use?
25 parts, built around the TPS61090_1_2. 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 ProMicro BOOST KiCad files?
From the clayton13/ProMicro repository on GitHub, at the commit this page was made from: the board is BOOST/ProMicro_BOOST.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ProMicro BOOST design in my own project?
Its repository states no licence, so its author keeps all rights: ask clayton13 before reusing the design.
