Questions
How big is the Solarpannel project PCB?
It measures 74 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Solarpannel project use?
11 parts, built around the BC548. 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 Solarpannel project KiCad files?
From the ragavarshini3/Solar_Panel repository on GitHub, at the commit this page was made from: the board is solarpannel_project.kicad_pcb and its schematic solarpannel_project.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Solarpannel project design in my own project?
Its repository states no licence, so its author keeps all rights: ask ragavarshini3 before reusing the design.
