Nextion Enhanced 2.4 inch HMI Display Resistive Touch Screen 5V TFT LCD 320x240 for Arduino ESP32 Board (NX3224K024)

- -Nextion NX3224K024 enhanced display is widely used in beauty equipment, smart home devices, household appliances, 3D printer, instrumentation etc. - -Compared with NX3224T024, NX3224K024 add new functions: support save data to Flash, GPIO, larger flash capacity and faster CPU. - -Nextion enhanced 2.4 display is a 5V device, but many development boards are 3.3V. It won't make the display power up. - -To ensure Nextion 2.4 enhanced display work as expected, it's recommended to supply power via power adapter, not usb to ttl or boards. - -Uploading TFT file via sd card is faster than the usb to ttl, but pls ensure card: FAT32 format, only one tft file(no folder), and no more than 32GB.

Product description

Nextion Editor Software

-The Enhanced Series hardware feature of 3.5″ and above is more powerful than Nextion Basic Series in terms of MCU, Flash Storage and SRAM.

-The Enhanced Series integrates RTC for keeping accurate time, EEPROM for users’ data storage and 8 digital GPIOs (4 PWM capable).

-For Nextion Enhanced, users also can develop HMI GUI project via Nextion Editor software, the easy Drag-and-Drop components and simple ASCII text based instructions will dramatically reduce HMI project development workloads.

-Easy-to-Use Nextion HMI software

-ASCII text based instructions over serial

-Assignable attribute value components at runtime

-Drag-and-Drop components for GUI design and interaction

-User Event Code pane for GUI interaction and peripheral MCU communication

(Note: If your HMI project was developed via 0.53 or prior version Nextion Editor, we recommend you to use the LTS version for project maintenance as the latest version is not fully compatible with your exsisting source code and GUI desgin.)

Questions & Answers

Q1: Can Nextion display be used with other MCU?

A: Nextion works with many MCUs, but we only offer Library for arduino and Linux. You need to develop Lib for other MCUs, and all instructions must strictly follow Nextion Instruction Set

Q2: How to upload the designed project?

A: USB to TTL module, and SD card.

Q3: Can Nextion read file in SD card?

A: No, SD card is only used to upload TFT project file.

Q4: My project is successfully made in Nextion Editor. How to get the TFT file?

A: Choose HMI file in Nextion Editor -Click "Compile" and it'll show "Compile Successful!" in the bottom of software -Choose "File","TFT file output" -Click "Output" and save TFT file.

Q5: Can I output the TFT file in Nextion screen?

A: No

Q6: I want to update my project. Why the TFT file can not be revised?

A: The file in Nextion Editor is HMI, and the output one is TFT. You should edit the HMI file in software.

Q7: Why Nextion Editor shows "Can not open this file (Your HMI file is made by low version Editor)?

A: The project is made in old version of Nextion Editor. You need to download the newest version.

Q8: The Nextion display "Model does not match" "File Infor ERROR!". How to solve it?

A: The TFT file was made in another model number, you need to reselect right model number in Nextion Editor.

Q9: How to upload a project via SD card?

A: Prepare a SD card ( FAT32 format and less than 32GB) -Copy TFT file from PC to SD card (ensure only one TFT file in it) -Insert SD card into Nextion card slot -Power on Nextion -File uploaded automatically and displays "Update Successed!" after completed -Power off Nextion -Remove SD card -Power on and project will show on Nextion.
