CP2102 USB to TTL Serial Converter Module - UART STC Downloader

The CP2102 USB to TTL Serial Module is a professional-grade bridge controller designed to facilitate seamless communication between a PC and microcontrollers via UART. Based on the stable Silicon Labs CP2102 chipset, this module provides a reliable alternative to cheaper CH340 converters, offering higher baud rate stability and broad driver compatibility across Windows, macOS, and Linux. It features a standard 6-pin breakout including DTR, RXD, TXD, VCC (5V/3.3V), and GND, making it perfectly suited for programming Arduino Pro Mini, ESP8266, and STC series microcontrollers. The module is equipped with a self-recovery fuse for USB port protection and onboard LEDs to monitor data transmission in real-time. The included 5 DuPont wires allow for immediate, solderless connection to your project board.

Key Features:

• Stable CP2102 Chipset: Provides a robust Virtual COM Port for high-speed serial debugging.
• DTR Pin for Auto-Reset: Enables one-click programming for Arduino and STC boards.
• Selectable 3.3V/5V Power: Onboard voltage regulator provides regulated power for target devices.
• Full Handshaking Support: Compatible with all standard asynchronous serial data bus signals.
• USB Port Protection: Integrated resettable fuse safeguards your computer from short circuits.
