Questions

How big is the Electronicload PCB?

It measures 54.5 × 80 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Electronicload use?

64 parts, built around the ADS1115IDGS, TLC272CD, AMS1117-3.3 and AMS1117-5.0. 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 Electronicload KiCad files?

From the GM4AJK/electronicload repository on GitHub, at the commit this page was made from: the board is Hardware/ElectronicLoad/ElectronicLoad.kicad_pcb and its schematic Hardware/ElectronicLoad/ElectronicLoad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Electronicload design in my own project?

Its repository states no licence, so its author keeps all rights: ask GM4AJK before reusing the design.
