Nextion NX4832f035 is a 3.5 Discovery series SMART HMI Touch display having a resistive touch screen. The discovery series of Nextion displays are cost-effective HMI solutions based on STM32GO ARM Cortex-M0+ 64MHz Onboard MCU Processor. In the discovery series when the Deep Sleep Mode is activated, the devices working current is down to 0.25 mA. Your Battery Powered HMI device will last a longer working time with such a low power consumption. Compared to the Nextion basic series the discovery series reaches up to 30% more performance improvement.

Next Discovery NX4832f035 3.5 Resistive Touchscreen Display is so simple to the interface that it can easily work with Arduino, Raspberry Pi, ESP8266, ESP32, PIC Microcontroller, AVR controller, ARM Microcontroller and you wont believe it will work even with basic 8051 microcontrollers basically it will work with any board or Microcontroller that has UART port.

Nextion includes a hardware part (a series of TFT boards) and a software part (theNextion editor). The Nextion TFT board uses only one serial port to communicate. Nextion editor has mass components such as button, text, progress bar, slider, instrument panel etc. to enrich the interface design. And the drag-and-drop function ensures that users spend less time in programming. With the help of this WYSIWYG editor, designing a GUI is a piece of cake.

1. 3.5 LCD-TFT Resistive HMI touch display module
2. 480 x 320 screen resolution
3. RGB 65K true-to-life colours
4. Onboard ARM Cortex-M0+ 64MHz MCU
5. 3584 Byte SRAM
6. 16 MB Flash memory
7. XH2.54 4 Pins (+5V, TX, RX, GND) TTL serial interface .

This TFT display is big bright and colorful! 480×320 pixels with individual RGB pixel control, this has way more resolution than a black and white 128×64 display.

As a bonus, this display has a resistive touch screen attached to it already, so you can detect finger presses anywhere on the screen. This display has a controller built into it with RAM buffering so that almost no work is done by the microcontroller.

This 3.5-inch SPI Touch Screen Module is wrapped up into an easy-to-use breakout board, with SPI connections on one end. If you’re going with SPI mode, you can also take advantage of the onboard MicroSD card socket to display images.

The 3.5-inch display doesn't have a built-in level shifter, so it's advised to use only 3.3v. Using a node MCU would be more suitable cause it provides only 3.3v. if you are using a 5v microcontroller like the Arduino UNO, MEGA, Using a level shifter would give you the appropriate voltage needed to operate the LCD without damaging it.

This product has 4 Dot Matrix LED’s cascaded to form a single LED Display to allot more area to the user on the display.

Connecting the two modules is also very easy. Only connect the output pins of the previous breakout board to the input pins of the new module, thus with such arrangement, you can connect as many DOT LED Modules to the Arduino as you wish!!! Great……

The MAX7219 Dot Led Matrix Module is a serial input common-cathode driver that interfaces micro-controllers to LED matrices. All common micro-controllers can be connected to this module by using a 4-wire serial interface. Each output can be addressed without refreshing the entire display. This module requires only 3 I/O lines for driving the display, making it ideal for your microcontroller projects. Only one external register is used to set the segment current of each LED.

Requires only three IO ports can drive a dot! No flashing dot matrix display! Support cascade!
