Complete HMI display with touchscreen. This screen can be controlled serially via a UART port and also has GPIO outputs that can be controlled via the Nextion software. The graphical interface of this module can also be programmed via an SD card or via the UART connection.
Decide for yourself what the screen looks like and program the interface with the touchscreen yourself. For examples and library's: see this Github.

The enhanced Nextion screens have a number of advantages over the normal Nextion screens:

  • Built-in RTC

  • Screen resolution: 320x240 pixels
  • Screen brightness: 0 ~ 180 nits (adjustable by 1%)
  • Touchscreen type: Resistive
  • Flash storage: 16MB
  • EEPROM: 1024 bytes
  • RAM: 3584 bytes
  • Instruction buffer: 1024 bytes
  • Colors: 64K (65536)
  • Available GPIO pins: 8x (of which 4 are PWM)
  • SD card slot, FAT32. Suitable for up to 32 GB SD card
  • Cable (4 pins) included with micro USB power adapter

Product FAQ

This is not possible in most cases. Most development boards (including Uno, Mega, NodeMCU, D1 Mini V3, etc.) have a diode between the 5V pin and the USB input that lowers the voltage. If the voltage from the 5V pin is lower than the required minimum of the device (see specifications) then it cannot function properly. In addition, many development boards can only provide little power. This can also cause it to malfunction. Using an insufficient power supply can even damage the device. Therefore, make sure that you use a suitable power supply and that it is connected correctly. It is advised to verify the supply voltage by measuring it.

In most cases, this is caused by insufficient power supply condition. Nextion HMIs require a good quality power supply. When the power supply provides too little current, has too low a voltage and/or generates too much ripple, several problems can arise, such as:

  • Flashing
  • Blurred screen
  • Freeze
  • Damage to the HMI

A good quality CE-approved power supply is required that can supply enough current and has the correct voltage. If necessary, measure the voltage directly on the Vcc and GND pins of the HMI.
