Included with your Nextion screen you find the connection cable for the screen. It's a 4-wire cable with a Red (5-8v), Blue (TX), Yellow (RX) and Black (GND)lead.
WARNING: If you connect 5V to RX, TX or GND, your screen is total-loss
- Connect the TX (Yellow) lead to the RX on your device (Raspberry, USBtoTTL adapter or Modem board)
- Connect the RX (Blue) lead to the TX on your device
- Connect the GND (Black) lead to the GND of your device
- Connect the 5V (Red) lead to the 5V of your device (minimal voltage should be 5V for a proper working)
USB-to-TTL adapter
You can use a USB-to-TTL adapter (they are cheap: 1 to 2 US$) to connect the Nextion device to your Raspberry or Computer. Be sure its supporting UART / CH340(G) for a proper working.
WARNING
Your Nextion device needs 5V-8V. Less voltage could damage your device in the long run
