Questions
How big is the ActiveLoad PCB?
It measures 85.7 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ActiveLoad use?
71 parts, built around the ATXMEGA32E5-AU, OPA2170AID, LM7321MA and L78M12CV. 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 ActiveLoad KiCad files?
From the jakubprzybytek/ActiveLoad repository on GitHub, at the commit this page was made from: the board is KiCad/ActiveLoad/ActiveLoad.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ActiveLoad design in my own project?
Its repository states no licence, so its author keeps all rights: ask jakubprzybytek before reusing the design.
