7" Nextion HMI LCD Touch Display

While waiting for 2, 7" Enhanced screens to be delivered, I figured I'd buy one of these, even thought it's "Basic." I want to get started on my project that requires the speed of the Enhanced screen. First, as usual, RobotShop got it shipped and delivered FAST!!!! Even during Covid, the speed is impressive. (just 2-3 days or so). When I first connected the screen, it did startle me because the LED lighting was flickering and the Demo would reboot the screen over and over. I thought for sure that I got a dud screen. But then, I realized 2 things. 1) I needed to provide the screen 5V at 450mA. I was only supplying around 100mA. Thus, flickering and resetting. Then, I threw together a quick test with the Nextion Editor with a full screen, very colorful picture, some animated pictures, 2 buttons, a progress bar, a bunch of larger-profile fonts (just to take up memory) and some other elements. When I sent this test to the display, using Nextion editor 0.53! (not 0.58 which is super buggy), the display went through a firmware update! THIS IS GOOD! Since then, the screen has been running 24/7 under test and has had zero problems. I really REALLY love these screens. So easy to use. Oh and for those of you who also love these screens but are burdened by the HUGE Nextion Library files, you can FULLY use these screens WITHOUT A LIBRARY! Just search YouTube for Nextion without library. You should find some seriously amazing tutorials by Cheap Controls. This man shows you how to do everything without libraries. Not only do you save tons of memory but it's much more efficient and faster to send/receive to the Nextion. Hope that helps.

The 2 Nextion displays arrived in good conditions those were well packaged, the shipping was fast. The displays allows to make fast developments, recommended!

The notifications and process was seamless and helpful

Les notifications et le processus étaient transparents et utiles

Both displays arrived in very good conditions, the service was good, those are very useful for make fast HMI, I'm using those for several projects and works fine! Recommended!
