ENHANCED SERIES INTRODUCTION
The Nextion Enhanced Series has 7 HMI display sizes including 2.4”, 2.8″, 3.2”, 3.5”, 4.3”, 5.0” and 7.0”.
What’s the difference between Enhanced Series and Basic Series?
— The Enhanced Series hardware feature of 3.5″ and above is more powerful than 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 Enhanced Series, users also can develop the HMI GUI project via the free Nextion Editor software, the easy Drag-and-Drop components and simple ASCII text based instructions will dramatically reduce the HMI project development workloads. The integration of RTC, EEPROM and digital GPIOs enhances your HMI project features and functions.

ACCESSORIES
NEXTION MIDI I/O INTERFACE
Two 4-pin XH connectors for 5V power supply, TX, RX and GND allow this interface to be easily daisy-chained between either a power supply / USB to TTL serial adapter like the Nextion Foca Max, or any MCU (Arduino, etc.) on one side (J1) and a Nextion HMI display on the other side (J2). The on-board switch SW1 allows to select between 2 modes:
* PRGM: RX + TX signals are directly routed from J1 to J2 which allows to program the device on J2 by the device on J1 while the MIDI interface is idle.
* MIDI I/O: RX + TX signals from the device on J2 are converted and linked to the MIDI IN and MIDI OUT 5-pin DIN sockets.
NEXTION MICRO SD EXTENDER
1. Feel hard to reach the micro SD card slot?
2. Have to disassemble the product enclosure for the HMI project update?
3. Other extension tools are not working properly?
The Nextion Micro SD card extender helps you to access the SD card slot of the Nextion HMI display more conveniently. It supports the FAT32 Micro SD card as well as all series of Nextion HMI displays compatibilities.
NEXTION BOX SPEAKER FOR INTELLIGENT SERIES AUDIO PLAY
The BOX speaker is for the use of 4.3″, 5.0″, 7.0″, 10.1″ intelligent series HMI display without enclosure.
Input Power：1.5W
Frequency Range: 100Hz-3KHz
Connector：1.25mm pitch 2-pin female connector (1.25T-2-2A)
Wire Length: 250mm
Size: 31*28*14.8mm
FOCA MAX- USB TO TTL CONVERTER BOARD
Foca Max is a USB to TTL serial converter board with 5.5V2A output. it integrates a high power and energy-efficient DC-DC chip of TPS54331 for a wide voltage input with small voltage ripple. For USB to TTL conversion, the Foca Max can be power supplied by USB only or USB together with external DC 8-26V, The USB and external DC power supplies are isolated by using a diode (SS34) to avoid the current backflowed between them.
Note: as for the Nextion HMI display size less than 4.3”, you can only use the USB for power supply, size large than 4.3”, a external DC 8-26V for power supply is recommended.
EXPANSION BOARD FOR NEXTION DISPLAY I/O EXTENDED
The first expansion board for Nextion Enhanced and Intelligent HMI displays.
– for use with any of the 2.4″, 2.8″, 3.2″, 3.5″, 4.3″, 5.0″, 7.0″ Enhanced and Intelligent models.
Supports the Enhanced and Intelligent Nextion’s 8 Digital/PWM GPIOs
The board includes 6 buttons, 1 LED, 1 Piezo buzzer, and 0.1″/2.54mm breakout:Esc (IO 0),
Enter (IO 1), Left (IO 5), Right (IO 2), Up (IO 4) and Down (IO 3)LED (IO 6) and small PWM Piezo buzzer (IO 7).
NEXTION IO ADAPTER
The Nextion IO Adapter is made specially to work with Nextion Enhanced and Intelligent HMI Display Series
– for use with any of the 2.4″, 2.8″, 3.2″, 3.5″, 4.3″, 5.0″, 7.0″, 10.1″ Enhanced and Intelligent models.
This small board breaks out the Nextion’s GPIOs to 0.1 inch /2.54 mm headers,allowing users to conveniently connect external devices to the Nextion’s Digital/PWM GPIOs.
