NX4848E040-011C – Nextion 4.0″ Edge Series HMI Touch Display

Product detailed description

Nextion Edge NX4848E040-011C is a touch HMI display with a 4.0" diagonal, 480 × 480 pixel resolution, and capacitive touch, capable of handling the entire device operation instead of your microcontroller. You can design the graphical interface in the free Nextion Editor, upload it to the internal 120MB flash memory, and the control unit then simply sends values and receives touch events via UART. The large active area combined with a compact module size of 82.8 × 82.8 mm makes it suitable for control panels, HVAC systems, 3D printers, or dispatching and measuring applications.

Some of the main features and benefits of Nextion Edge:

• UART Serial Communication: The display is controlled via a UART serial bus, making it easy to communicate with various microcontrollers and single-board computers.
• Easy Programming: The display comes with UI design software, allowing you to easily create buttons, graphs, text fields, and other control elements without the need for complex programming.
• Intuitive Interface: Nextion series products are designed with your user-friendliness in mind, making it easy for you to create and adjust the interface according to your needs.
• Capacitive Touch: The touch layer responds smoothly and accurately just like a phone, with no need for calibration and no pressure required on the display.
• Slim Edge Series Profile: The module is only 5.2 mm high, making it easy to integrate into flat panels and control cabinet doors.
• Interaction Capabilities: With this display, you can easily create interactive projects that allow you to enter data and perform various actions.
• On-board Expansion: You have 8 digital GPIOs with PWM, a microSD card slot and an integrated real-time clock (RTC) with a CR1220 backup battery available.
• Wide Compatibility: The display is compatible with popular platforms such as Arduino, Raspberry Pi and ESP32 microcontrollers, simplifying integration into various projects.
• Overall, Nextion Edge is a great choice for developers and enthusiasts who want to quickly and easily create a user interface for their HMI projects without the need for complex programming.

Note:

• The display does not include a USB interface or speaker – use a microSD card or a USB-TTL converter to upload the project.
• Data pins operate with 3.3 V logic. If you are connecting a 5V microcontroller, use a level shifter.
• This product is not a standalone functional unit and may require professional installation.
• Product images are for illustrative purposes only and may sometimes differ from the actual appearance of the item. However, this does not change its basic properties.
