About this product

Working

This is a 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 ports. This 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 that 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).

Pinouts

This module has 6 pin breakout which includes

•GND = Should be common to microcontroller ground.

•3V3 = Optional output to power external circuit up to 50mA.

•5V = Optional output to power external circuit upto 500mA

•DTR/RST = Optional output pin to reset external microcontrollers like Arduino.
