4.1 ഡ്രൈവർ ഇൻസ്റ്റലേഷൻ

Before connecting the module to your computer, it is recommended to install the necessary drivers. The CH343G chip requires specific drivers for proper recognition and functionality across different operating systems.

• വിൻഡോസ്: Download the latest CH343G driver from the Waveshare official website or the chip manufacturer's website. Run the installer and follow the on-screen instructions. Verify installation in Device Manager under 'Ports (COM & LPT)'.
• മാക് ഒഎസ്: Download the appropriate CH343G driver for your Mac OS version. Install the driver and restart your computer if prompted. You can verify installation using the 'System Information' utility.
• Linux: Most modern Linux distributions include CH34x drivers in their kernel. If the module is not recognized automatically, you may need to install the `ch34x` kernel module or download and compile the driver from the manufacturer's website. Use `ls /dev/ttyUSB*` or `dmesg | grep tty` to check for device recognition.
• ആൻഡ്രോയിഡ്: For Android devices, driver support is typically integrated into the system or handled by specific applications that utilize serial communication.

4.2 Hardware Connection and Pinouts

The module provides a 6-pin header for UART communication. Ensure correct pin connections to your target device.

• വിസിസി: Power output (5V or 3.3V, selected by jumper). Connect to the target device's power input.
• GND: Ground. Connect to the target device's ground.
• TXD: Transmit Data. Connects to the target device's RXD (Receive Data) pin.
• RXD: Receive Data. Connects to the target device's TXD (Transmit Data) pin.
• RTS#: Request To Send (active low). Connects to the target device's CTS (Clear To Send) pin if hardware flow control is used.
• CTS#: Clear To Send (active low). Connects to the target device's RTS (Request To Send) pin if hardware flow control is used.

5. പ്രവർത്തന നിർദ്ദേശങ്ങൾ

5.1 TTL Level Selection

The module supports multiple TTL voltage levels (5V, 3.3V, 2.5V, 1.8V). The 3.3V and 5V levels can be selected via an onboard jumper. For 2.5V or 1.8V, external configuration might be required depending on the specific application and target device.

• To select 5V TTL level, place the jumper cap on the 5V pins.
• To select 3.3V TTL level, place the jumper cap on the 3V3 pins.

Caution: Ensure the selected TTL level matches the voltage requirements of your target device to prevent damage.

5.2 അടിസ്ഥാന ആശയവിനിമയം

Once the drivers are installed and the module is connected to your computer and target device:

• Open a serial terminal program (e.g., PuTTY, Tera Term, Arduino Serial Monitor).
• Identify the COM port (Windows) or `/dev/ttyUSBx` (Linux/Mac) assigned to the module.
• Configure the serial terminal settings to match your target device's UART parameters (baud rate, data bits, parity, stop bits, flow control). Common baud rates include 9600, 115200, etc.
• You should now be able to send and receive data between your computer and the target device.

6. പരിപാലനം

To ensure the longevity and reliable operation of your Waveshare CH343G module, follow these maintenance guidelines:

• സംഭരണം: Store the module in a dry, anti-static environment when not in use.
• കൈകാര്യം ചെയ്യൽ: Avoid touching the electronic components directly. Use anti-static precautions (e.g., anti-static wrist strap) when handling the module to prevent electrostatic discharge (ESD) damage.
• വൃത്തിയാക്കൽ: If necessary, gently clean the module with a soft, dry cloth. Do not use liquids or abrasive cleaners.
• ശാരീരിക സമ്മർദ്ദം: Avoid bending or applying excessive force to the module or its connectors.

7. പ്രശ്‌നപരിഹാരം

• Module not recognized by computer:
  • Ensure drivers are correctly installed for your operating system.
  • Try a different USB port or USB cable.
  • ഡ്രൈവർ ഇൻസ്റ്റാൾ ചെയ്തതിനുശേഷം നിങ്ങളുടെ കമ്പ്യൂട്ടർ പുനരാരംഭിക്കുക.
• No communication with target device:
  • Verify TXD and RXD connections are crossed (TXD of module to RXD of device, and RXD of module to TXD of device).
  • Check that the GND pins of both the module and the target device are connected.
  • Confirm that the selected TTL voltage level (5V/3.3V) matches the target device's requirements.
  • Ensure baud rate, data bits, parity, and stop bits settings in your serial terminal match the target device.
  • If using hardware flow control (RTS/CTS), ensure these pins are correctly connected and enabled in your software.
• Power LED (PWR) not lit:
  • Ensure the module is properly connected to a powered USB port.
