4. Посібник із налаштування
4.1. Встановлення драйвера
Before connecting the module to your computer, it is recommended to install the necessary drivers. While this module uses an FT232RL compatible chip, it typically utilizes FTDI drivers. You can usually find the latest drivers on the official FTDI website or by performing a web search for "FTDI drivers".
- Підтримувані операційні системи: Windows 95/98/98se/ME/2000/XP/Win7 (32-bit and 64-bit), and partial Vista support.
- Примітка: Windows 8 is generally not supported. However, some users have reported success with Windows 10 and 11 after manual driver installation.
- Installation Steps (Windows Example): Download the appropriate driver package. Extract the files. Right-click on the .inf files (usually two of them) and select 'Install' before plugging in the adapter.
4.2. Випtage Вибір
The module supports both 3.3V and 5.5V (5V) operation. A jumper on the module allows you to select the desired voltage for the VCC pin. Ensure the jumper is correctly placed to match the operating voltage of your target device to prevent damage.
4.3. Фізичне підключення
- Підключення до комп'ютера: Use a Mini USB cable to connect the module to an available USB port on your computer.
- Connect to Target Device: Wire the module to your target device (e.g., Arduino Pro Mini) using the appropriate pins. Pay close attention to the pinout.
5. Інструкція з експлуатації
5.1. Pinout Description
The module features the following pins:
- ДТР: Data Terminal Ready. Often used for automatic reset on microcontrollers like Arduino.
- RXD: Receive Data. Connects to the TX (Transmit) pin of your target device.
- TX: Transmit Data. Connects to the RX (Receive) pin of your target device.
- VCC: Power Supply Output. Provides either 3.3V or 5.5V, depending on jumper setting. Connect to the power input of your target device.
- ЦТС: Clear To Send. Used for hardware flow control (less common for simple serial communication).
- GND: Ground. Connects to the ground of your target device.
5.2. Using with Arduino Pro Mini
To upload sketches to an Arduino Pro Mini, connect the module as follows:
- Module DTR to Pro Mini DTR
- Module RXD to Pro Mini TXD
- Module TX to Pro Mini RXD
- Module VCC to Pro Mini VCC (ensure correct voltagе вибір)
- Module GND to Pro Mini GND
Once connected and drivers are installed, your computer should recognize the module as a virtual COM port. You can then select this COM port in your Arduino IDE and upload sketches.
5.3. Communication Indicators
The RXD and TXD LEDs on the module will flash during data transmission and reception, indicating active serial communication.

9. Вирішення проблем
- Модуль не розпізнано: Ensure drivers are correctly installed. Try a different USB port or cable.
- Помилки зв'язку:
- Verify RXD and TX pins are correctly cross-connected (RXD to TX, TX to RX).
- Check that the baud rates on both the computer and the target device match.
- Confirm the correct COM port is selected in your software.
- Target Device Not Powering On/Damaged: Двічі перевірте об'ємtage selection jumper (3.3V/5.5V) to ensure it matches your target device's requirements. Incorrect voltage can damage components.
- Немає активності світлодіодів: Ensure the module is properly connected to the computer and receiving power. Check for any physical damage.
