Questions
How big is the Solar NiMH emulation PCB?
It measures 45 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Solar NiMH emulation use?
21 parts, built around the LM317DCYR. 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 NiMH emulation KiCad files?
From the peteEH/USB-battery-source repository on GitHub, at the commit this page was made from: the board is solar_NiMH_emulation/solar_NiMH_emulation.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Solar NiMH emulation design in my own project?
Its repository states no licence, so its author keeps all rights: ask peteEH before reusing the design.
