Questions
How big is the Eboard PCB?
It measures 87 × 87 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Eboard use?
103 parts, built around the CP2102, ESP32-PICO-D4, SRV05-4 and TP4056. 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 Eboard KiCad files?
From the pacew/eboard repository on GitHub, at the commit this page was made from: the board is eboard/eboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Eboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask pacew before reusing the design.
