Description
PL2303 USB to TTL Converter
 
USB to UART Converter is a very useful tool for Embedded Systems. If you 
haven’t one, please try to buy it. It will definitely boost development speed of 
projects which uses UART modules like interfacing GSM, GPS, Bluetooth, 
Wi-Fi …  By using it we can easily study these modules by sending data directly 
from your PC and analyzing the received data in your computer display without 
programming a microcontroller. Here we will use PL2303, one of the most popular 
USB to UART Converter manufactured by Prolific Technology Inc.
 
Installing Driver
 
Before starting using UART, you need to install driver for PL2303. You can install 
driver in two ways. If your system is connected to internet, you can install driver 
using windows update otherwise you need to download the driver setup file and 
install it. First we will see, installing driver using windows update.

 

With Internet Connection
 
  • Verify that your internet connect is OK and plug in the PL2303 USB to UART Converter to you PC.
  • Windows Update will automatically search for driver and install instantly if it is available.
  • If the automatic update doesn’t work, go to Control Panel >> System and Security >> Device Manger

They serve PL2303hxa this module instead of this one PL2303.\r\nPricing is reasonable. It is out of service since 2012. Very difficult to use this product in win10. Maybe I am not going to buy this if I know before.
