CP2102 is a USB to UART IC from Silicon Labs. It is my favourite converter IC and I have been using USB to RS232 module and USB to TLL modules based on CP2102 for couple of years without any issues. CP2102 is a cheaper alternative to the costlier ftdi FT232 IC but cp2102 is a bit difficult to solder as it comes in QFN-28 package and is very small (just 5mmx5mm) in size. The main advantage of CP2102 is that no extra external components are required.
CP2102 USB to ttl IC is used in lot of Arduino UNO Clones, arduino Nano, Node MUC and even in ESP32 Development boards. In this tutorial I will provide you with step by step process to install CP2102 USB Driver in windows.
You can download CP2102 driver from below
Step by Step Installation of CP2102 Drivers
Initially connect your hardware having CP2102 USB to Serial IC to your PC. In the device manager it will show “CP2102 USB to UART Bridge Controller” (as shown in below figure) which means that your PC has detected the drivers but please note the “!” sign which indicated cp2102 drivers have not been installed.
Now extract the “CP210x_Windows_Drivers” in a folder and in that you will find applications named “CP210xVCPInstaller_x64” & “CP210xVCPInstaller_x86”. If your system is 64 bit then run “CP210xVCPInstaller_x64.exe” application and if it is 32 bit then run “CP210xVCPInstaller_x86” application.
Once you run your application it will show you the welcome screen click “Next” on the screen. Then the license Agreement screen is shown select “I agree” and then on “Next”.
Just relax now the CP2102 drivers will start installing…..and within few seconds completed screen will be displayed.
Once installed it will show driver successfully installed. Now go again back to device manager and there you will see that the driver has been successfully been installed and a com port has been allotted. In below image you can see that “com4” has been allotted for cp2102 IC in my laptop.
Drivers for the CP2102 have now been installed successfully. I have tested this drivers and installation process in Windows XP, windows 7. Will test is soon on Windows 8 & windows 10.
You can see in above image that Port Number 4 has been allocated to this IC. If you want you can even change the virtual com port number from Device Manager.
