    Most ESP32 boards have a small USB-to-UART bridge chip next to the USB socket. It’s the reason your computer sees a “port”, and the wrong or missing driver for it is a common reason an upload fails.

    Generic board sketch: USB socket on the left, a small chip labelled USB-UART chip next to it with an arrow saying look here, then the ESP32 module. Notes say some boards have no bridge chip and use native USB.

    Look closely at the chip near the USB socket on your board and reply with:

    1. Your board name
    2. The text printed on that chip (for example CP2102, CH340, FT232, or none because your board uses the chip’s native USB)
    3. Did it work on your computer without installing a driver?

    We’ll collect the answers into a beginner-friendly list. Tip: a phone camera with zoom makes the tiny print easier to read.

    Close-up sketch of a small dark chip: the top line of print is usually the part name such as CP2102, CH340 or FT232, other lines are batch or date codes. Tip: use phone zoom.
