Questions
How big is the ESPDrive PCB?
It measures 44 × 64 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ESPDrive use?
58 parts, built around the AP63201WU, AP63203WU, LTV-827S and AO3400A. 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 ESPDrive KiCad files?
From the Ehryk/ehryk.github.com repository on GitHub, at the commit this page was made from: the board is Circuits/ESPDrive/ESPDrive.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESPDrive design in my own project?
Its repository states no licence, so its author keeps all rights: ask Ehryk before reusing the design.
