2. In the Pi OS configuration graphical interface, enable I2C and serial port, and disable the serial monitor function.

3. By default, the /dev/ttyAMA0 serial port is enabled, but you need to edit the file to enable the /dev/ttyAMA2 serial port.

Run the command:
sudo nano /boot/firmware/config.txt
Add the following lines:

dtoverlay=uart2
dtoverlay=uart3
Save the file and exit.

The serial port mappings are as follows:

Code:
Serial Port    Device File    Physical Pins (Board)    BCM Pins (GPIO)

UART2    /dev/ttyAMA1    Pin 27 (TXD) / 28 (RXD)    GPIO 0 / 1

UART3    /dev/ttyAMA2    Pin 13 (TXD) / 14 (RXD)    GPIO 4 / 5

UART4    /dev/ttyAMA3    Pin 7 (TXD) / 21 (RXD)    GPIO 8 / 9

UART5    /dev/ttyAMA4    Pin 29 (TXD) / 30 (RXD)    GPIO 12 / 13

4. When you first open Node RED and import a Node flow, you will be automatically prompted to install the required plugins. Click "OK" to install all the plugins automatically.
