SPECIFICATION:

• Model name/number:PL2303HX Adopt imported controller PL2303HX, which can stabilize the flash with high speed
• 500mA self-recovery fuse for protection
• Two data transmission indicator can monitor data transfer status in real time
• Reserve 3.3V and 5V pin interface, easy for the DDWRT of different voltage system that needs power
• The entire board is coated by the high quality transparent heat-shrinkable sleeve, making the PCB in insulation state from outside,
• so that the board won’t be burnt down by material shortcut.
• Electrostatic package ensures the board will not be damaged before use

DESCRIPTION: The PL2303 PL2303HX USB to TTL converter module is another commonly used device for serial communication between a computer and microcontrollers, such as Arduino boards or other electronic devices. It converts USB signals to TTL-level signals, enabling communication through the serial interface.

The module typically consists of a small PCB with a USB connector on one end and a 5-pin header or individual pins on the other end. The 5-pin header includes pins labeled as VCC, GND, TXD, RXD, and 3V3 (or 5V). Here is a brief description of each pin:

VCC: Connects to the power supply pin (usually 5V or 3.3V) of the microcontroller or device you are communicating with. Make sure the voltage matches the requirements of your specific application.

GND: Connects to the ground pin of the microcontroller or device.

TXD: Transmits data from the USB-to-TTL converter to the microcontroller. Connect this pin to the RX (receive) pin of the microcontroller.

RXD: Receives data from the microcontroller to the USB-to-TTL converter. Connect this pin to the TX (transmit) pin of the microcontroller.

3V3 or 5V: This pin provides power (either 3.3V or 5V) output from the converter module, which can be used to power the microcontroller or device, if required. However, be cautious not to exceed the maximum power limitations of your microcontroller.

To use the PL2303 PL2303HX USB to TTL converter module, follow these steps:

Connect the module to your computer: Plug the USB connector of the module into an available USB port on your computer. Wait for your operating system to recognize and install any necessary drivers automatically. If required, manually install the drivers provided by the manufacturer.

Connect the module to the microcontroller or device: Make the following connections between the module and the microcontroller or device:

Connect VCC to the power supply pin (5V or 3.3V) of the microcontroller.

Connect GND to the ground pin of the microcontroller.

Connect TXD to the RX pin of the microcontroller.

Connect RXD to the TX pin of the microcontroller.

Optionally, connect the 3V3 or 5V pin to the power input of the microcontroller, if necessary.

Verify the connection: Open your preferred serial communication software or the Arduino IDE on your computer. Select the correct serial port corresponding to the PL2303 USB-to-TTL converter in the software.

Start communicating: You can now send and receive serial data between your computer and the microcontroller or device. Use the appropriate serial communication functions or libraries in your code to establish communication and exchange data.
