QSG136: CP2102N Mini Evaluation Kit
Quick-Start Guide

The CP2102N-MINIEK kit is designed to showcase the various
features of the CP2102N USBXpress® devices.

These highly-integrated USB-to-UART bridge controllers provide a simple solution for
updating RS-232 designs to USB using a minimum of components and PCB space. By
eliminating the need for complex firmware and driver development, the CP2102N devi­ces enable quick USB connectivity with minimal development effort.

Getting Started

1. Getting Started

1. Download and Install the Latest Virtual COM Port (VCP) Drivers.

The Virtual COM Port (VCP) drivers enable the CP2102N to appear as a standard COM port. Download the latest version of driv­ers from the Silicon Labs website:

In most cases, select the default option without serial enumeration.

2. Set Up Your Kit.

a. Provide power to the board by connecting the mini USB connector to the PC using a mini USB cable (not provided). When a

connection has been established successfully, the LED (marked in the picture) lights up.

3. Detect Your Device.

The CP2102N device will appear as a COM port in Device Manager in Windows. As a virtual COM port, the CP210x functions
identically to a real COM port from the reference point of both the host application and the serial device, and it can support serial
device control requests defined in the Microsoft Win32® Communications API.
