Questions
How big is the DC Electronic Load PCB?
It measures 150 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DC Electronic Load use?
245 parts, built around the STM32F373C8T6, STM32F446VET6, LMP2022MM and MAX5215GUA+. 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 koson/KicadProject repository on GitHub, at the commit this page was made from: the board is Commercial/DC Electronic Load/Revision 3/DC-Electronic-Load.kicad_pcb. 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 states no licence, so its author keeps all rights: ask koson before reusing the design.
