Questions

How big is the KiBoxLite H PCB?

It measures 50 × 85 mm and has 4 copper layers, 1.6 mm thick.

What parts does the KiBoxLite H use?

161 parts, built around the ESP32-WROOM-32E-N4, MAX13487EEA and WPM2015-3/TR. 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 KiBoxLite H KiCad files?

From the Samael312/ESPKI repository on GitHub, at the commit this page was made from: the board is Hardware/KiBoxLite_H.kicad_pcb and its schematic Hardware/KiBoxLite_H.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the KiBoxLite H design in my own project?

Its repository states no licence, so its author keeps all rights: ask Samael312 before reusing the design.
