Questions
How big is the RC controller PCB?
It measures 86 × 96.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RC controller use?
27 parts, built around the BOB-12009, NODEMCU-32SLUA, XL1509-5.0 and SS310. 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 RC controller KiCad files?
From the CUERT-dev/ElectricalRndD_TeamDev repository on GitHub, at the commit this page was made from: the board is Esp32_RCcontrollerV0/RC_controller.kicad_pcb and its schematic CozySolder/CozySolder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RC controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask CUERT-dev before reusing the design.
