4.1. Connect ESP32-S2-MINI-1 and ESP32-S2-MINI-1U to PC

Connect the ESP32 board to the PC using the USB cable. If device driver does not install
automatically, identify USB to serial converter chip on your ESP32 board (or external
converter dongle), search for drivers in internet and install them.

The drivers above are primarily for reference. Under normal circumstances, the drivers
should be bundled with and operating system and automatically installed upon connecting
one of the listed boards to the PC.

4.2. Check Port on Windows

Check the list of identified COM ports in the Windows Device Manager. Disconnect ESP32-
S2 and connect it back, to verify which port disappears from the list and then shows back
again.
