Generic ESP-01 USB to Serial Adapter Board, CH340

The Generic ESP-01 USB to Serial Adapter Board with CH340 is an interface board designed for programming and serial communication with ESP8266 ESP-01 WiFi modules. It integrates a CH340 USB-to-UART converter to provide reliable data transfer between a computer and the ESP-01 via a standard USB connection. The board supplies regulated 3.3 V power and exposes GPIO and UART pins required for flashing firmware and testing. It is compatible with common development environments and operating systems that support CH340 drivers. Typical applications include firmware programming, debugging, and rapid prototyping of ESP-01–based IoT projects.
