CP2102 USB to TTL UART Serial Converter Module 6Pin Black

Description

Product Overview

The CP2102 USB to TTL UART Serial Converter Module is a compact, high-performance serial communication adapter that bridges the gap between a computer’s USB port and a microcontroller’s UART (Universal Asynchronous Receiver/Transmitter) interface. Based on the industry-leading CP2102 bridge controller from Silicon Labs, this module creates a virtual COM port on your computer, allowing you to program, debug, and communicate with embedded systems that lack native USB connectivity .

Whether you are working with an Arduino Pro Mini, ESP8266, ESP32, STM32, or other microcontrollers, this module provides a simple, reliable solution for serial communication . The board features a standard 6-pin interface with labels printed on the silk screen, plus dedicated 3.3V and 5V power output pins, and includes a self-recovery fuse for protection against accidental short circuits .

With a compact PCB size of just 26.5mm × 15.6mm and a full-speed USB 2.0 interface, this converter is perfect for programming, firmware updates, and serial debugging of a wide range of embedded systems . It’s a direct replacement for similar adapters like the FT232 and is widely recognized for its reliability and cross-platform compatibility .

Key Features

• Genuine CP2102 Chipset: Based on the high-performance Silicon Labs CP2102 USB-to-UART bridge controller with full hardware handshaking support .

• Broad Baud Rate Support: Supports baud rates from 300 bps up to 1 Mbps or even 921,600 bps, making it suitable for high-speed data transmission and programming .

• 6-Pin Layout with Auto-Reset: Standard 6-pin 2.54mm pitch pinout (DTR, RX, TX, VCC, 5V, GND) featuring a DTR line for automatic reset of Arduino-compatible boards during upload .

• Dual Voltage Output: Provides both 3.3V and 5V power outputs to supply your target device. The 5V output is limited to 500mA (typical USB standard) .

• Integrated Protection: Features a self-recovery fuse that protects your computer’s USB port and the target device in the event of an accidental short circuit .

• Visual Status LEDs: Three onboard LEDs provide clear status indication: POWER (red), TXD (data transmission), and RXD (data reception) for real-time activity monitoring .

• USB 2.0 Compliant: Meets USB 2.0 full-speed (12 Mbps) specifications, ensuring compatibility with modern computers and operating systems .

• No External Crystal Required: The chip features an integrated clock, eliminating the need for external crystal oscillators and simplifying design and use .

• Cross-Platform Driver Support: Works out of the box or with simple driver installation on Windows, macOS, and Linux, with Silicon Labs providing official drivers .

• Extra I/O Pin Support: In addition to the main 6 pins, the RX, TX, RTS, and CTS pins are accessible on the side for advanced debugging and hardware handshaking .
