NX4848E028-011C – Nextion 2.8″ Edge Series HMI Touch Display

Product detailed description

Nextion Edge NX4848E028-011C is a touch HMI display with a 480 × 480 pixel resolution and a capacitive touch layer, which transfers the entire graphical interface from the microcontroller to the display itself. You can design screens, buttons, sliders, and graphs in the free Nextion Editor, upload them to the display via a microSD card or serial link, and simply send and receive short text commands via UART in your code. The square format and larger active area are ideal for control panels for heating, aquariums, coffee machines, technological switchboards, or a home IoT dashboard.

Some key 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 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 5.11 mm high, so it can be easily integrated into flat enclosures and panels.
• 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 battery backup available.
• Broad 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.

Package contents:

• 1× Nextion Edge NX4848E028-011C touch HMI display

Note:

• The display data pins operate with 3.3 V logic. If you are connecting a 5V microcontroller, use a level shifter.
• Route the power supply separately from a 5 V / 1 A source – the microcontroller's USB port may not provide enough current for the display.
• 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.
