Questions
How big is the ESP32-UART PCB?
It measures 37.5 × 20 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32-UART use?
14 parts, built around the AMS1117-3.3 and SP0503BAHTG. 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 ESP32-UART KiCad files?
From the vedanthiwale/USB_UART_INTFCE repository on GitHub, at the commit this page was made from: the board is ESP32-UART.kicad_pcb and its schematic ESP32-UART.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32-UART design in my own project?
Its repository states no licence, so its author keeps all rights: ask vedanthiwale before reusing the design.
