CP2102 Micro USB to TTL

The CP2102 Micro USB to TTL Converter Module is a high-performance USB-to-UART bridge designed for reliable serial communication between a PC and embedded systems. It is based on the CP2102 integrated chip, which combines USB controller, transceiver, oscillator, EEPROM, and UART interface into a single compact solution.

This module allows computers without a native serial (COM) port to communicate with microcontrollers via a virtual COM port over USB. It is widely used in programming, debugging, and data exchange for development boards and embedded systems.

The module supports a wide range of baud rates and provides stable, fast, and efficient data transmission. It is compatible with major operating systems, making it a universal tool for electronics developers.
