CP2102 Black USB to UART serial adapter

Information about this module is generated with the help of AI. The description may be incomplete, inaccurate, or subject to change.
CP2102 Black is a compact USB to UART adapter for serial communication between a computer and electronic circuits. The adapter uses the Silicon Labs CP2102 and provides a virtual COM port when connected to a computer through USB.

The module is suitable for programming, configuration and troubleshooting of microcontrollers and other devices with a UART interface. Typical applications include Arduino, ESP8266, ESP32, STM8 and other development boards with serial communication.

The module provides TXD and RXD for serial data communication together with GND as the common signal ground. TXD on the CP2102 is normally connected to RX on the target device and RXD to TX. The module also provides DTR and RTS control signals that can be used for reset and programming functions on compatible development boards.

The module has both +5V and 3V3 connections. +5V is supplied from the USB connection while 3V3 provides a 3.3 V connection from the modules power supply. Always check the voltage levels of the target circuit before connecting the module.

Additional control signals include DCD, DSR, CTS, RI and RST. These signals are mainly intended for advanced serial communication and are normally not required for basic UART communication.
