Waveshare 7,5 inch E-Paper Display HAT Module V2-kit 800x480 resolutie 3,3 v/5v E-Ink elektronisch scherm met ingebouwde controller SPI-interface compatibel met Raspberry Pi/Jetson Nano/Arduino/STM32

Excellent feature to adjust periodically if necessary. Needs no power to keep the messages displayed so very economical. Update is easily done, the only thing needed to make it esthetically looking is an 3D printed case derived from the internet.

Nice contrast, it does leave some ghosting, but that's solvable in software by increasing refresh a little bit.

This works exactly as promised. The display already comes with all cables needed and the documentation on the website is great and with good examples. I got it working first on a raspberry pi and then on an arduino within minutes.

This Waveshare Universal e-Paper Driver Board is an excellent choice for anyone working with e-paper displays. It supports a wide range of Waveshare SPI e-Paper Raw Panels, offering flexibility for different project needs.The onboard ESP8266 WiFi SoC is a great addition, allowing for wireless control and updating of the display. It makes it easy to create projects that can display information from the internet or integrate with other WiFi-enabled devices.

Having used two of these screens over the past 4 months I can confidently say that these are poor quality screens.They simply do not render images consistently over time.I have experienced two things:1) Blacks turning into light greys over time (~ 2 days). Blacks in certain parts of the screen simply will not show up as black anymore.2) Inconsistent pixel activation. Essentially random pixels being activated in large streaks when they are not supposed to be

L'écran a cessé de fonctionner après quelques semaines. Des recherches sur internet ont montré que c'est un problème courant, et je n'ai pas réussi à le résoudre. L'écran m'a finalement été remboursé, et il a tout de même parfaitement fonctionné pendant quelques semaines, donc bon achat si vous avez plus de chance que moi.

I brought the screen having done a little research and got exactly what I expected! I'm using it to display a screen of information such as weather, news, local train times and the temperature in my home which updates every five minutes. I found it pretty easy to use a Raspberry Pi Zero WH to drive it using code based on the samples WaveShare provide online.The only disappointment is that it does not support partial screen update, as far as I can tell. It doesn't take too long to update the screen in full though, and my application is not time critical, so all good.
