Questions
How big is the Energy Portel PCB?
It measures 61.4 × 66 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Energy Portel use?
27 parts, built around the NE555D and SPL PL90. 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 Energy Portel KiCad files?
From the Evan3445/Solder-PCB repository on GitHub, at the commit this page was made from: the board is Energy Portel.kicad_pcb and its schematic Energy Portel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Energy Portel design in my own project?
Its repository states no licence, so its author keeps all rights: ask Evan3445 before reusing the design.
