Questions
How big is the Load PCB?
It measures 36 × 25 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Load use?
20 parts, built around the LM358. 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 Load KiCad files?
From the Kutty-GT/OCPC_Learning repository on GitHub, at the commit this page was made from: the board is load.kicad_pcb and its schematic load.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Load design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kutty-GT before reusing the design.
