Questions
How big is the UINIO USB UART CP2102 PCB?
It measures 33.7 × 20.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UINIO USB UART CP2102 use?
25 parts, built around the CP2102 and LESD5D5.0CT1G. 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 UINIO USB UART CP2102 KiCad files?
From the uinika/UINIO-USB-UART-CP2102 repository on GitHub, at the commit this page was made from: the board is UINIO-USB-UART-CP2102.kicad_pcb and its schematic UINIO-USB-UART-CP2102.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the UINIO USB UART CP2102 design in my own project?
Its repository states no licence, so its author keeps all rights: ask uinika before reusing the design.
