Questions
How big is the DC Electronic Load PCB?
It measures 160.7 × 100.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DC Electronic Load use?
95 parts, built around the ATMEGA328-PU, LM324, LM358 and MCP3204-CI/P. 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 DC Electronic Load KiCad files?
From the tomeh2/DC-Electronic-Load repository on GitHub, at the commit this page was made from: the board is DC Electronic Load.kicad_pcb and its schematic DC Electronic Load.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DC Electronic Load design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
