DTR Active low Data Terminal Ready output pin. It shows that it is ready to accept the data. RTS Active low Ready-to-Send output pin It supports the Xon/Xoff handshake mechanism. It supports the Xon/Xoff handshake mechanism. The pin configuration in tabular are detailed as below: Pin Name Function VCCIO Positive Power Supply pin GND Ground pin RST Reset pin TXD UART Serial Transmission pin RXD UART Serial Reception pin CTS Active low Clear-to-Send input pin. The pinout of the compact CP2I02 UART module is as shown: Pin Configuration TX/RX LED: These LEDs indicate the functioning of the respective pins. Power port: VCCIO and GND pins supply input power to the module. UART Hardware control ports: RTS and CTS are hardware control signals for durable data connection between transmitter and receiver. UART data transmission port: The module uses this asynchronous serial communication port for information transfer.

Modem Interface Signal portĬontrol port: The port is responsible for power management and resetting of the module.

CP2102 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.
