Questions
How big is the ESPRadiator PCB?
It measures 50 × 57 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESPRadiator use?
49 parts, built around the AP63203WU, LTV-827S, IRLZ44N and AO3401A. 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 ESPRadiator KiCad files?
From the Ehryk/ehryk.github.com repository on GitHub, at the commit this page was made from: the board is Circuits/ESPRadiator/ESPRadiator.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESPRadiator design in my own project?
Its repository states no licence, so its author keeps all rights: ask Ehryk before reusing the design.
