Questions

How big is the Repowered Electronic Load Controller PCB?

It measures 175 × 25 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Repowered Electronic Load Controller use?

43 parts, built around the 74HC4051, LP2985-33DBV and MBR0540. 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 Repowered Electronic Load Controller KiCad files?

From the AdamC19/Electronic_Load_HW repository on GitHub, at the commit this page was made from: the board is Repowered_Electronic_Load_Controller/Repowered_Electronic_Load_Controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Repowered Electronic Load Controller design in my own project?

Its repository states no licence, so its author keeps all rights: ask AdamC19 before reusing the design.
