Dual USB to UART Converter Module with CP2105, Two Independent Serial Ports for Debugging and Embedded Development
The 7Semi CP2105 Dual UART USB Converter Module is a compact USB-to-serial interface designed to provide two independent UART ports from a single USB connection. Built around the Silicon Labs CP2105 USB-to-UART bridge controller, the module enables simultaneous communication with two serial devices, making it ideal for debugging, programming, data logging, and testing multiple embedded systems. Its plug-and-play operation ensures quick setup on Windows, Linux, and macOS without requiring complex hardware configuration.
The module is well-suited for developers, engineers, and hobbyists working with Arduino, ESP32, STM32, Raspberry Pi, GPS modules, wireless communication devices, and other UART-based electronics. Clearly labelled TX, RX, 5 V, 3.3 V, and GND pins simplify wiring, while the compact PCB design makes it easy to integrate into laboratory setups, production testing, and portable embedded applications.
