Questions
How big is the Solarpower module PCB?
It measures 35.6 × 25.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Solarpower module use?
17 parts, built around the AP3015AKTR-G1 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 Solarpower module KiCad files?
From the RTX17LEO/Tiny-Solar-Power-Supply-Module repository on GitHub, at the commit this page was made from: the board is solarpower module.kicad_pcb and its schematic solarpower module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Solarpower module design in my own project?
Its repository states no licence, so its author keeps all rights: ask RTX17LEO before reusing the design.
