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 driv-
ers from the Silicon Labs website:

http://www.silabs.com/vcpdrivers

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.
