Nextion Enhanced NX8048K070 is a 7″ Resistive or Capacitive Programmable Touch Display with an Optional Enclosure

Orange Pi Development Boards

Nextion displays are designed to be controlled by MCU boards with the user interface designed in Nextion Editor drag-and-drop tool. ITEAD Studio launched them in 2015, and I played with Nextion 2.4″ and 5.0″ models, but at the time, I found the Windows only Nextion Editor program not to be that user-friendly and inconvenient to use, as for example, UI designs do not automatically scale across all display sizes. The company is now back with a 7″ model, available with resistive or capacitive touch panel, and featuring an ARM7 processor exposing 8 GPIOs.

Nextion Enhanced NX8048K070 (_011) specifications:

  • CPU – ARM7 processor @ 108 MHz with 8K RAM, 1024 EEPROM, 1024 bytes instruction buffer
  • Storage – 32MB flash memory, micro SD card slot
  • Display – 7″ TFT display with resistive or capacitive panel; resolution: 800×480; 65K colors; adjustable brightness: 0 to 230 nit
  • Expansion – 8x GPIOs including 4x PWM, 4-pin serial interface to MCU board
  • Misc – Built-in RTC + battery slot
  • Power Supply – 5V/2A through micro USB to 2-pin power board
  • Dimensions – Display + board only: 181 x 108 mm; enclosure: 218 x 150 x 22.50 mm
  • Weight – Display + board only: 268 g; with enclosure: 598 grams

The display can work in standalone mode controlling external hardware through the 8 GPIOs, or connected to an MCU board over serial. You’ll find a few more technical details in the Wiki. The UI designed in Nextion Editor is stored in the flash memory or micro SD card, and the MCU board can receive / send commands to get user input/update the display. Nextion Editor is still a Windows only program, but if my memory serves me well, it can also work with Linux through Wine using a /dev/ttyUSB0 to COM1 redirect.

There are four models: NX8048K070_011N without touch support (no sold for now), NX8048K070 with resistive touch sold for $81.90, as well as NX8048K070_011C and NX8048K070_011R both sold with enclosure, and either resistive or capacitive touch respectively for $88.00 and $108.00. It appears the model without enclosure has been selling for a few months already, and the models with enclosure are new.
