The pinout of the compact CP2I02 UART module is as shown: Pin Configuration CP2102 ComponentsĬP2102 USB to UART Bridge module consists of CP2102 chip, Modem Interface Signal port, Control port, UART data transmission plus control ports, power port, and built-in TX & RX LEDs. The tutorial is a guide to the pinout, specifications, features, working, and applications. However, it requires drivers to start the serial communication.

The device is embedded with two voltage regulators and matching pull-up resistors.CP2102 is compatible with Windows/Linux/Mac OS-X/OS-9 and existing COM ports. Moreover, it contains a PROM of 1024 bytes and a 48 MHz internal oscillator. The module supports handshaking and also processes the command requests made by the USB host to control the activities of the asynchronous serial UART port. CP2102 possesses a high-performance, inbuilt transceiver for serial data along with suspend/resume signals for the energy control of the chip and external circuitry also. It is a single CP2102 chip USB to UART Bridge with 12Mbps USB full speed. CP2102 UART module is the upgraded version of RS-232 Communicator introduced by Silicon Labs.
