Questions
How big is the Carico elettronico PCB?
It measures 99.5 × 99.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Carico elettronico use?
92 parts, built around the LM324, LM358, MCP4821-E/P and L7805. 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 Carico elettronico KiCad files?
From the dario0603/electronic_load repository on GitHub, at the commit this page was made from: the board is KiCad/Carico elettronico 1.0/Carico elettronico.kicad_pcb and its schematic KiCad/Carico elettronico 1.0/Carico elettronico.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Carico elettronico design in my own project?
Its repository states no licence, so its author keeps all rights: ask dario0603 before reusing the design.
