Product Description:

The USB TTL converter UART module is a compact and reliable interface for connecting microcontrollers, development boards, and embedded devices to a computer via USB. It enables serial communication between your PC and devices such as Arduino, ESP8266, ESP32, STM32, or other UART-based systems.

Built with a high-quality chip (commonly FT232RL, CH340G, or CP2102), this module ensures stable data transmission and easy plug-and-play installation across multiple platforms (Windows, Linux, macOS).
