2PC USB 2.0 to UART TTL 6PIN Module, CP2102 Serial Converter Adapter with 3.3V/5V Dual Power for Arduino ESP32 ESP8266 STM32

2PC USB 2.0 to UART TTL 6PIN Module is a high-performance serial converter built around the Silicon Labs CP2102 chip, serving as a perfect replacement for FT232 modules. It converts USB signals to TTL UART signals, enabling seamless communication between computers and microcontrollers, development boards, or serial devices. Compliant with USB 2.0 full-speed (12Mbps) standard, it supports baud rates from 300bps to 1Mbps for efficient data transfer. The 6-pin header (TXD, RXD, GND, 3.3V, 5V, RST) offers dual 3.3V /5V power output, compatible with most TTL-level devices like Arduino Pro Mini, ESP8266, ESP32, STM32, and STC microcontrollers.

Equipped with POWER, TXD, and RXD LEDs, the module displays real-time operating status for easy monitoring. The integrated self-recovery fuse provides short-circuit protection, safeguarding your computers USB port and connected devices. It supports multiple operating systems including Windows, macOS, Linux, and Android, requiring only driver installation to create a virtual COM port for plug-and-play use. Ideal for firmware uploading, serial debugging, data logging, and device flashing, this compact and reliable module is a must-have tool for electronics enthusiasts, developers, and hobbyists.
