Questions
How big is the BrainDeadMPPT PCB?
It measures 45 × 80 mm and has 4 copper layers, 1.6 mm thick.
What parts does the BrainDeadMPPT use?
77 parts, built around the LTC4015EUHF#PBF, NC7SZ04L6X, 1N4448HLP and BZT52C15LP. 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 BrainDeadMPPT KiCad files?
From the lucansky/BrainDeadMPPT repository on GitHub, at the commit this page was made from: the board is BrainDeadMPPT.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BrainDeadMPPT design in my own project?
Its repository states no licence, so its author keeps all rights: ask lucansky before reusing the design.
