Questions

How big is the Wheeler PCB?

It measures 92.5 × 101 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Wheeler use?

25 parts, built around the ESP32-WROOM-32E, L293D, CH340G and AMS1117. 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 Wheeler KiCad files?

From the Gex-devs/RC_CAR repository on GitHub, at the commit this page was made from: the board is WheelerPCB/Wheeler.kicad_pcb and its schematic WheelerPCB/Wheeler.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Wheeler design in my own project?

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