Questions
How big is the Dummy load PCB?
It measures 72.5 × 82.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dummy load use?
27 parts, built around the LM358 and IRFZ44N. 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 Dummy load KiCad files?
From the picli3/dummy-load repository on GitHub, at the commit this page was made from: the board is dummy_load.kicad_pcb and its schematic dummy_load.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dummy load design in my own project?
Its repository states no licence, so its author keeps all rights: ask picli3 before reusing the design.
