Nextion is a Human Machine Interface (HMI) solution combining an onboard processor and memory touch display with Nextion Editor software for HMI GUI project development. Using the NEXTION Editor software, you can quickly develop the HMI GUI by drag-and-drop components (graphics, text, button, slider, etc.) and ASCII text-based instructions for coding how components interact at the display side. Nextion HMI display connects to peripheral MCU via TTL Serial (5V, TX, RX ,GND) to provide event notifications that peripheral MCU can act on, the peripheral MCU can easily update progress, and status back to Nextion display utilizing simple ASCII text-based instructions. Comparing with Basic Series, the Discovery Series has a better MCU performance, the same functionalities as Basic, and Lower Price. That’s Nextion Discovery Series Products.

Package include: Nextion NX3224F024 HMI Display*1, XH2.54 4P wire*1, power supply test board*1.
Note: the small power supply test board and connecting wire inside the package allow you to test if the electrical supply is enough or not. See the image below on how to use it.

Electronic Characteristics

Operating Voltage
Operating CurrentVCC=+5V, Brightness is 100%90mA
Normal SLEEP Mode (lowpower=0)4.5mA
Deep SLEEP Mode (lowpower=1)0.25mA

1. Power supply recommend:5V, 500mA, DC.

2. In deep sleep mode, the wake-up time will be longer, the data will be probably lost when the serial port receive is receiving the wake-up command. Therefore, it is recommended to send a void command and delay 50ms before operating.
