Questions

How big is the Test encoders PCB?

It measures 74.5 × 67 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Test encoders use?

7 parts, built around the ESP32-DEVKITC-VE. 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 Test encoders KiCad files?

From the mora200217/lukas repository on GitHub, at the commit this page was made from: the board is test_encoders/test_encoders.kicad_pcb and its schematic PCB /lukas_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Test encoders design in my own project?

Its repository states no licence, so its author keeps all rights: ask mora200217 before reusing the design.
