PL2303HX USB to TTL UART RS232 Serial Adapter

Product Description

The PL2303HX Serial Converter provides a stable and cost-effective way to add a virtual COM port to any PC. It features a standard USB Type-A plug on one end and five male header pins on the other, allowing for direct connection via jumper wires to your target board. The module is engineered with dual voltage outputs, enabling it to power small 3.3V sensors or 5V microcontrollers directly from the USB bus. Integrated TX and RX LED indicators provide immediate visual feedback of data transmission, which is critical for identifying communication errors during the initial stages of hardware development.

Key Features

• Dual Power Output: Provides both 3.3V and 5V power pins, eliminating the need for an external power supply when programming low-power devices.

• High-Speed Data: Supports a wide range of baud rates for everything from slow industrial sensors to high-speed firmware uploads.

• Diagnostic LEDs: Includes onboard Transmit (TX) and Receive (RX) indicators that flash during active data exchange.

• Over-Current Protection: Features a built-in fuse to protect your computer's USB port from accidental shorts on the target board.

• Slim Form Factor: The narrow PCB design ensures it won't block adjacent USB ports on your laptop or hub.

Technical Details

• Flow Control: Supports hardware flow control (RTS/CTS) depending on the specific driver and wiring configuration.

• Compatibility: Works with standard terminal software like PuTTY, Tera Term, and the Arduino IDE Serial Monitor.

• Housing: Transparent heat-shrink sleeve provides basic environmental protection.
