Questions
How big is the Tiny Hi3861 PCB?
It measures 35 × 18 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tiny Hi3861 use?
40 parts, built around the CP2102N-A01-GQFN24 and HX9193-33GB. 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 Tiny Hi3861 KiCad files?
From the imliubo/Tiny-Hi3861 repository on GitHub, at the commit this page was made from: the board is 1.Hardware/Tiny-Hi3861.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tiny Hi3861 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
