Questions

What parts does the Solar nRF.kicad pro use?

54 parts, built around the ATTINY402-SSN, MDBT42TV-AT, BQ25504RGT and IRLML6402. 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 nRF.kicad pro KiCad files?

From the PocketConcepts/Solar_nRF repository on GitHub, at the commit this page was made from: the board is HW/Solar_nRF/Solar_nRF.kicad_pro.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 nRF.kicad pro design in my own project?

Its repository states no licence, so its author keeps all rights: ask PocketConcepts before reusing the design.
