The Silicon Labs Dual CP2105 USB to UART Bridge Enhanced COM Port is a USB-to-UART (Universal Asynchronous Receiver-Transmitter) adapter, often used in embedded systems and other devices that require a serial communication interface. The CP2105 is a chipset from Silicon Labs designed to provide a USB interface for UART-based communication, often used in applications like microcontroller programming, serial data logging, or communication between computers and embedded devices.

The Windows driver for the CP2105 allows your computer to recognize the USB-to-UART adapter and communicate with the devices attached to it, via virtual COM ports (VCPs). These virtual COM ports appear in Device Manager and are used by software to interact with the connected hardware over serial communication.
