Questions
How big is the ControlBoard PCB?
It measures 62.1 × 82.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ControlBoard use?
26 parts, built around the ESP32-C6-DEVKITC-1-N8. 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 ControlBoard KiCad files?
From the wadengroff/Junior_Design repository on GitHub, at the commit this page was made from: the board is pcb/controlBoard/controlBoard/controlBoard.kicad_pcb and its schematic pcb/controlBoard/controlBoard/controlBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ControlBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask wadengroff before reusing the design.
