Description:

The PL2303HX chipset is a popular solution for USB to serial conversion due to its reliable performance and ease of use. This converter cable module also supports a wide range of operating systems, including Windows, Mac, Linux, and Android, which makes it a versatile tool for developers, hobbyists, and makers. The cable module can be used for a variety of applications, including debugging, programming, and communication with other devices. It is a useful tool for anyone who needs to connect a TTL serial device to a computer or other host device.

 

Principle of Work:

The 1m 4 pins USB to TTL Serial Converter PL2303HX Cable Module works by converting the TTL (Transistor-Transistor Logic) level signals from a serial device to the USB (Universal Serial Bus) level signals that a computer can understand. It uses the PL2303HX chipset to facilitate this conversion. When the module is connected to a computer via a USB port, the computer recognizes it as a COM port, and the user can communicate with the connected serial device as if it were directly connected to the computer's serial port. The module receives data from the serial device via the RX pin, converts it into USB signals, and sends it to the computer. Similarly, it receives data from the computer via USB signals, converts it into TTL signals, and sends it to the serial device via the TX pin. The PL2303HX chipset used in this module is designed to handle serial communication and is compatible with a wide range of operating systems, including Windows, Mac, Linux, and Android. It supports a variety of data formats, baud rates, flow control protocols, and automatic handshake protocols, making it a versatile and reliable tool for serial communication.

 

Pinout:

  • VCC: provides power to the device being connected (usually 5V)
  • GND: provides a ground connection for the device
  • RX: receives data from the device
  • TX: transmits data to the device

 

Applications: 

  • Programming and debugging microcontrollers: The module can be used to program and debug microcontrollers that use a TTL serial interface, such as Arduino, ESP32, and Raspberry Pi.
  • Industrial automation and control: The module can be used to communicate with various industrial equipment and devices, such as sensors, actuators, and programmable logic controllers (PLCs).
  • Robotics and automation: The module can be used to communicate with various robotic systems and automation devices that use a TTL serial interface.
  • Communication and networking: The module can be used to establish serial communication between different devices, such as computers, microcontrollers, and sensors, over a USB connection.
  • Home automation: The module can be used to control various home automation systems and devices that use a TTL serial interface, such as smart home devices, sensors, and security systems.
  • Education and research: The module can be used as a tool for educational and research purposes, such as learning about serial communication, studying different protocols, and developing new applications.

 

Circuit:

To connect an HC-06 module to a PL2303 USB to Serial Bridge Controller, connect the following pins:

  • HC-06 TXD (gray or white wire) to PL2303 RXD (green wire)
  • HC-06 RXD (green wire) to PL2303 TXD (white wire)
  • HC-06 GND (black wire) to PL2303 GND (black wire)
  • HC-06 VCC (red wire) to PL2303 VCC (red wire)
  • The PL2303 controller will act as a bridge between the HC-06 module and a computer, allowing serial communication over a USB connection.

Drivers needed:

 

Example:  

To communicate with an Android phone and a PC using the HC-06 module and the serial converter, this process involves setting up a Bluetooth connection between the Android phone and the HC-06 module and using the serial converter to bridge the communication between the phone and the PC via the TX and RX pins you can follow these steps:

  1. Connect the HC-06 module to the serial converter as described in the previous answer, making sure that the TX and RX pins are connected properly.
  2. Connect the serial converter to the PC via a USB port, and install the necessary drivers for the PL2303 chipset if needed.
  3. Install a terminal emulator app on your Android phone, such as Termux, Serial Bluetooth Terminal, or BlueTerm.
  4. Pair your Android phone with the HC-06 module via Bluetooth. You may need to enter a PIN code to complete the pairing process (0000 or 1234 as default).
  5. Open the terminal emulator app on your Android phone, and set the baud rate, data bits, stop bits, and parity bits to match the settings of the serial converter.
  6. Send commands or data from the Android phone to the serial converter by typing them into the terminal emulator app and pressing enter. The commands or data will be transmitted to the HC-06 module via Bluetooth, and then to the serial converter via the TX pin.
  7. Receive data from the PC on your Android phone by sending commands or data from the terminal emulator app to the serial converter via the TX pin. The data will be transmitted to the HC-06 module via Bluetooth, and then to the Android phone for display in the terminal emulator app.

Comparisons:

The PL2303HX and FTDI232 are both USB to TTL serial converters that can be used to communicate with microcontrollers, sensors, and other electronic devices. Here are some comparisons between the two:

  1. Chipset: The PL2303HX uses a PC-PL2303HX chip, while the FTDI232 uses an FTDI FT232RL chip. Both chips are widely used and have good driver support, but the FTDI232 is generally considered to be more reliable and compatible with a wider range of operating systems.
  2. Pinout: The PL2303HX and FTDI232 have slightly different pinouts. For example, the DTR pin on the PL2303HX is not available.
  3. Baud rate: The PL2303HX supports a wider range of baud rates (75 to 128000) compared to the FTDI232 (300 to 115200), which may be useful for some applications.
  4. Price: The PL2303HX is generally less expensive than the FTDI232, which may be a consideration for budget-conscious projects.
  5. Compatibility: The FTDI232 is known to have better compatibility with some specialized hardware and software, such as certain radio equipment and programming tools, than the PL2303HX.
