Install USB-to-serial drivers for your operating system to enable communication with your device.

Modern operating systems often have built-in drivers. Try connecting your device first—if it's recognized, you don't need to install anything.

Used by many ESP32 development boards and some ESP8266 boards.

Common on budget ESP boards, NodeMCU clones, and some Arduino clones.

Used on some Arduino boards and professional development tools.

On Linux, you may need to add udev rules to access serial ports without root.

Add user to dialout group

sudo usermod -a -G dialout $USER
