            ## Flashing

            ### Browser (easiest)

            Download the `.bin` for your board above, then flash it in your browser — no drivers or tools needed:

            👉 **[https://www.espboards.dev/tools/program/](https://www.espboards.dev/tools/program/)**

            Works with Chrome, Edge, or Opera. Connect your ESP via USB, click **Connect to ESP**, select the `.bin` file, and flash.

            ### Command line

            ```bash
            esptool.py -p <PORT> write_flash 0x0 esp-scope-<variant>.bin
            ```

            Replace `<PORT>` with your serial port (e.g. `/dev/ttyUSB0` or `COM3`).
