NX4848E021-011C – Nextion 2.1″ Edge Series HMI Touch Display

Product detailed description

Nextion Edge NX4848E021-011C is a compact HMI touch display with a resolution of 480 × 480 pixels and a capacitive touch layer, allowing you to create a full-featured graphical device control without writing complex graphics code. You can design all graphics, buttons, charts, and animations in the free Nextion Editor environment and upload them directly to the display – your microcontroller then communicates with the display using simple text commands via a serial link. This saves the processing power and memory of the control unit, whether you are building a control panel for home automation, a 3D printer, an industrial machine, or a measuring instrument. The slim design of the Edge series (height of only 5.07 mm) is intended for installation in panels with minimal depth.

Some of the main features and advantages 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 modify 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.
• Edge Series Slim Profile: The module is only 5.07 mm high, making it easy to install in very shallow 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.
• 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.

Package contents:

• 1× Nextion Edge NX4848E021-011C 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.
