Questions
How big is the Ublink PCB?
It measures 67 × 54.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ublink use?
61 parts, built around the ESP32-WROOM-32U, CH340G, EL817-S1 and HF115F/005-1ZS3A. 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 Ublink KiCad files?
From the koraa/ublink repository on GitHub, at the commit this page was made from: the board is hardware/ublink.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ublink design in my own project?
Its repository states no licence, so its author keeps all rights: ask koraa before reusing the design.
