CP2102 USB 2.0 to TTL UART Serial Converter Module
The CP2102 USB 2.0 to TTL UART Serial Converter Module is a compact USB-to-UART bridge designed to establish serial communication between a computer and TTL-based electronic devices. Based on the Silicon Labs CP2102 chipset, the module integrates the USB transceiver, UART controller, oscillator, and EEPROM into a single device, requiring minimal external components while providing reliable serial communication.
The module is compliant with the USB 2.0 Full-Speed specification and supports communication speeds ranging from 300bps to 1.5Mbps. It features a standard USB Type-A connector on one side and a 6-pin TTL interface consisting of 3.3V, 5V, TXD, RXD, GND, and RST on the other, making it suitable for programming, debugging, firmware uploading, and serial communication with compatible microcontrollers and embedded systems.
Designed for developers, students, and embedded engineers, the CP2102 USB to TTL UART Serial Converter Module supports hardware and X-On/X-Off handshaking, USB suspend states, and line break transmission. Its compact form factor and broad operating temperature range make it suitable for laboratory, educational, industrial, and prototyping environments.
