Questions
How big is the Max2771eval PCB?
It measures 95 × 80.6 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Max2771eval use?
72 parts, built around the MAX2771ETI+, MAX8510EXK33+T and ATX-H11-F-24.000MHZ-F25-T. 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 Max2771eval KiCad files?
From the kamilkarp/max2771eval repository on GitHub, at the commit this page was made from: the board is hardware/max2771eval.kicad_pcb and its schematic hardware/max2771.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Max2771eval design in my own project?
Its repository states no licence, so its author keeps all rights: ask kamilkarp before reusing the design.
