Questions
How big is the Opensolar PCB?
It measures 60.5 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Opensolar use?
147 parts, built around the SM72295MA, SM72485MM, CH340G and SM72442MT. 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 Opensolar KiCad files?
From the junglejim8/opensolar repository on GitHub, at the commit this page was made from: the board is opensolar.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Opensolar design in my own project?
Its repository states no licence, so its author keeps all rights: ask junglejim8 before reusing the design.
