Questions
How big is the Down cp PCB?
It measures 88.9 × 85.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Down cp use?
396 parts, built around the CP2104EK, SRV05-4 and S9014. 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 Down cp KiCad files?
From the xiongyumail/ESP-Debugger repository on GitHub, at the commit this page was made from: the board is Down_cp.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Down cp design in my own project?
Its repository states no licence, so its author keeps all rights: ask xiongyumail before reusing the design.
