CP2102 Module USB to TTL Serial UART CP2102

Product Overview

The module described in the provided document is a USB to TTL CP2102 Converter Module. It serves as a USB-to-serial bridge that converts standard USB signals into TTL (Transistor-Transistor Logic) level serial signals. This enables direct serial communication (UART) between a computer or USB-enabled host and microcontrollers or embedded systems that lack native USB support.
