Questions
How big is the Usb2Uart PCB?
It measures 46.2 × 16.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Usb2Uart use?
46 parts, built around the ADM3485ARZ, ADUM1201AR, FT232RQ and DLW21SN900SQ2. 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 Usb2Uart KiCad files?
From the Kreyl/Usb2Uart repository on GitHub, at the commit this page was made from: the board is Usb2Uart.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usb2Uart design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kreyl before reusing the design.
