CP2102 Module is CP2102 based on highly integrated single-chip USB to TTL bridge IC. it requires the very minimum external components. The module has a built-in USB2.0 full-speed function controller, USB transceiver, crystal oscillator, EEPROM, and asynchronous serial data bus (UART). It supports a full-featured modem signal without any external USB device. This is a powerful tool for those who want to make PC interfaced projects or devices.

This module can be used with a laptop that does not have a standard serial port. It makes a virtual COM port using USB on the computer which can support various Baud rates for serial communication.
