Questions
How big is the Atomic01 PCB PCB?
It measures 86.5 × 71 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Atomic01 PCB use?
50 parts, built around the MT3608, TM1637, TP4056-42-ESOP8 and SS14. 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 Atomic01 PCB KiCad files?
From the rajeev2705/PROJECTS repository on GitHub, at the commit this page was made from: the board is Kicad Projects/Atomic 01 PCB/Atomic01 PCB.kicad_pcb and its schematic Kicad Projects/3.3V DC Buck Boost Converter/3.3V Buck Boost Converter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Atomic01 PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask rajeev2705 before reusing the design.
