Questions

How big is the KQC PCB?

It measures 100 × 42 mm and has 4 copper layers, 1.6 mm thick.

What parts does the KQC use?

80 parts, built around the RP2040, CC1101RGP, ESP-12F and W25Q32JVZPIQ. 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 KQC KiCad files?

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

Can I use the KQC design in my own project?

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