Questions
How big is the Current load PCB?
It measures 71.8 × 54.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Current load use?
54 parts, built around the LM324N, BS170 and BSS138. 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 Current load KiCad files?
From the jaycosper/current_load repository on GitHub, at the commit this page was made from: the board is current_load.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Current load design in my own project?
Its repository states no licence, so its author keeps all rights: ask jaycosper before reusing the design.
