USB to UART Bridge - TTL Signals - CP2102 Based (M2)

CP2102 chip from SiLabs 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. Hobbyists can use it as a powerful tool to make all kinds of PC interfaced projects. Most people know how to work with RS232 protocol but only few can use USB because of its complex nature. This module help all those who are comfortable with RS232/Serial Communication protocol, to build USB devices very easily.

How CP2102 USB-UART Converter works?

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. A ding sound from PC indicate proper connection. 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).
