Flashing

Extra steps required

Please read this section carefully.

On the first picture in the Media section below, aside the USB-C are two (extremely small!) buttons.

  • The "R" button is "Reset";
  • The "B" button is "Bootloader".

To flash, you need to enter bootloader mode. Follow these steps:

  • Unplug the board.
  • Hold down the "B" button.
  • Replug the board while holding it down.

If everything went correctly, you can now flash the board using a flashing tool like esptool. After flashing, press "R" to reset the board into normal boot mode.
