Chapter 1. Get Started
• CP210x: CP210x USB to UART Bridge VCP Drivers
• FTDI: FTDI Virtual COM Port Drivers
Please check the board user guide for specific USB to serial converter chip used. The drivers above are primarily for
reference. Under normal circumstances, the drivers should be bundled with an operating system and automatically
installed upon connecting the board to the PC.
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.
Figures below show serial port for ESP32 DevKitC and ESP32 WROVER KIT

Check port on Linux and macOS
To check the device name for the serial port of your ESP32-S2 board (or external converter dongle), run this command
two times, first with the board / dongle unplugged, then with plugged in. The port which appears the second time is
the one you need:
Linux
ls /dev/tty*
macOS
Espressif Systems 70
