Questions
How big is the MicroAtlas PCB?
It measures 20 × 32.8 mm and has 4 copper layers, 1.61 mm thick.
What parts does the MicroAtlas use?
38 parts, built around the W25Q32JVZPIQ, TPS2116DRL, TPS7A2033PDBVR-TP and LQG15HS47NJ02D. 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 MicroAtlas KiCad files?
From the Kev1n8088/MicroAtlas repository on GitHub, at the commit this page was made from: the board is MicroAtlas.kicad_pcb and its schematic MicroAtlas.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MicroAtlas design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kev1n8088 before reusing the design.
