The 7Semi CP2105 Dual USB to UART Converter Module provides two independent UART interfaces through a single USB Type-C connection. Powered by the Silicon Labs CP2105 USB bridge, it enables simultaneous communication with two embedded systems, making it ideal for firmware programming, debugging, industrial automation, LTE modules, ESP32, STM32, Arduino, and Linux-based applications.

Unlike traditional USB-to-UART adapters that provide only one serial interface, the CP2105 integrates two independent UART channels within a single USB connection. Each UART appears as a separate virtual COM port on Windows, Linux, and macOS, allowing users to program, monitor, and debug multiple embedded systems without requiring two separate USB adapters.

The module is built around the genuine Silicon Labs CP2105 USB bridge IC and features a USB Type-C connector, compact PCB design, and reliable high-speed communication for development, manufacturing, and field diagnostics.
