Whether you’re using an ESP32 or ESP8266 development board, it will almost always rely on a Silicon Labs CP2102 or CP2104 USB-to-UART chipset for programming and serial communication with a PC. This chipset acts as the bridge between the board and your computer, enabling firmware uploads, debugging, and serial monitoring. To function correctly, the appropriate CP210x drivers are required on your system. Without them, the board may not be detected or appear as an unknown device. These drivers ensure stable communication across Windows, macOS, and Linux platforms and are essential for tools like Arduino IDE, PlatformIO, and ESP-IDF.
