HJHYUL CP2102 USB to TTL Serial Adapter – 2.0 5Pin UART 1-Pack, Red

Enhance your development and debugging experience with this CP2102 USB 2.0 to TTL UART 6-Pin Serial Converter Module, designed for reliable communication between your computer and microcontrollers (MCUs). Ideal for developers, hobbyists, and engineers working with Arduino, ESP8266, STM32, STC, and other embedded systems.Key Features:Reliable CP2102 Chipset: Built around the stable and trusted CP2102 chip, which automatically creates a virtual COM port after driver installation. Ensures consistent performance and compatibility with a wide range of systems.USB Powered with 3.3V/5V Output: The module draws power from the USB port and provides output pins for 3.3V (max 40mA) and 5V, along with GND, TXD, RXD, and RST. All signal lines use 3.3V TTL logic (positive logic), making it compatible with most 3.3V or 5V devices.Onboard Indicator LEDs: Includes three LEDs—power/status LED remains ON when the driver is installed correctly, while TX and RX LEDs flash during communication. The higher the baud rate, the lower the brightness, allowing for easy visual monitoring of transmission activity.Flexible Baud Rate & Communication Format: Supports baud rates from 300 bps to 1 Mbps, and various serial communication settings:Data bits: 5, 6, 7, or 8Stop bits: 1, 1.5, or 2Parity: None, Odd, Even, or MarkBuffer & Flow Control Support: Built-in byte receive buffer and 640-byte transmit buffer. Supports hardware flow control and X-ON/X-OFF software handshake. Supports USB suspend mode via the SUSPEND pin and broken line (disconnection) detection.TTL vs RS232 Logic Explanation: This module uses TTL logic (0V = logic “0”; +3.3V or +5V = logic “1”), which is positive logic. In contrast, RS232 uses inverted signals (−12V to −3V = logic “1”; +3V to +12V = logic “0”).Wide Operating System Compatibility: Fully compatible with Windows 98SE, 2000, XP, Vista, 7, 10, 11, Mac OS 9/X, and Linux kernel 2.4 and above.Industrial Temperature Range: Operates reliably between −40°C to +85°C, suitable for harsh environments and industrial use.
