Serial convertor Module
CP2102 chip is a single chip USB to UART bridge IC. It requires minimal external components. CP2102 can be used to migrate legacy serial port based devices to USB.
This serial convertor module is an USB2.0 to TTL UART Converter module which is based on CP2102 Bridge by SiLabs. This module can be used with Laptop’s which don’t have standard serial port. This serial convertor module creates a virtual COM port using USB on your computer which can support various standard Baud Rates for serial communication.
You just need to install the driver using a setup file which automatically installs correct driver files for Windows XP/Vista/ 7. After driver installation, plug the module into any USB port of your PC. Finally a new COM port is made available to the PC.
The feature which makes it more convenient is the TTL level data i/o. So you don’t need to make a RS232 to TTL converter using chips like MAX232. The Rx and Tx pin can be connected directly to the MCUs pins (assuming 5v i/o).
