Questions
How big is the Solar Array PCB?
It measures 40 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Solar Array use?
36 parts, built around the BPW34. 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 Solar Array KiCad files?
From the PocketConcepts/Solar_nRF repository on GitHub, at the commit this page was made from: the board is HW/Solar_Array/Solar_Array.kicad_pcb and its schematic HW/Solar_Array/Solar_Array.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Solar Array design in my own project?
Its repository states no licence, so its author keeps all rights: ask PocketConcepts before reusing the design.
