Description
The CP2102 ICIntegrated Circuit is a common USB Serial Adapter found in many devices that converts USB signals to 2-wire UARTUniversal Asynchronous Receiver-Transmitter (TXTransmit, RXReceive) for 3.3V systems (the CP2102 input is 5V tolerant). It operates at USB Full Speed and supports baud rates from 300bps to 1Mbps.
For Linux OS the drivers are typically already installed in the kernel, but for Windows and Mac OS, the driver needs to be downloaded from the SciLabs website and installed.
The CP2102 IC has power pins (VCC, GND), data pins (TX, RX), and control pins (RI, DTR, DSR, DCD, RTS, CTR), defined in the table below. However, some modules may not include some or all of the control pins.Pin | Description |
---|---|
VCC | Power supply 3.3V |
GND | Common ground for power and logic. |
TX | UARTUniversal Asynchronous Receiver-Transmitter data transmit pin. This pin sends the serial output. |
RX | UARTUniversal Asynchronous Receiver-Transmitter data receive pin. This pin receives the serial input. |
RI | Ring Indicator Control Input. This pin is active low. |
DTR | Data Terminal Ready output. This pin is active low. |
DSR | Data Set Ready input. This pin is active low. |
DCD | Data Carrier Detect input that is usually present inside an RS-232 cable. |
RTS | Ready To Send control output. This pin is active low. |
CTR | Clear To Send control input. This pin is active low. |
