200x200 Resolution 1.54inch E-Ink Display Module Electronic E-paper Sreen with Embedded Controller SPI Interface Support Partial Refresh for Raspberry Pi/Arduino/Nucleo

Product went out of order after 3-5 hours of use. Grey noise appeared on screen and display is not reacting on any command anymore. I've contacted support, they've answered, so the support works pretty well (not more then a week to wait for an answer for each e-mail :) ). After very long e-mail conversation it appeared that GxEPD driver seems not to put the display to sleep properly. But to be honest I'm not quite sure that this is the true reason of the display's death. Just can not check this because have no other display and definitely will not order a new one.I've didn't get any refund. Requested a proper driver for ESP32, so will tell you if they will provide me with a proper one.So if using this with ESP32 and GxEPD first solve the "deep sleep" issues by calling commands from datasheet manually. Otherwise your display will die soon.Regarding the display itself: the image is not quite as crisp as I expected. When doing partial refresh (works on 2.9 b/w) there is a lot of artifacts on the edges of the refreshing rectangle. Sometimes, even after full refresh it lacks contrast. So overall quality is rather poor.So if it won't die if would be 3-4 star. And besides it's dead, if support was more helpful (at least by responding a little bit timely) it would be 2-3 stars.

This display is nice and the example code was enough to get me going pretty quickly. But from a Raspberry Pi Zero W it takes about 35 second to update the screen. ~30 to push the image to it then about 5 to actually refresh in which time it flashes inverted for a moment. I would not recommend this for anything live or updated constantly. Support told me it should be faster from a 3B+ but I have not tested that.

The device doesn't work, across arduino (with a waveshare shield) or on an RPi, using waveshare's own readme and git project will just cause the screen to cycle solid or blank with the C APIs.I'm really bummed this didn't work, I was looking forward to having a nice e-paper display.edit: I found the device does actually work from the python bindings. So while only 1/3 demos for it work correctly at least I can rule out that the hardware is bad. 3/5 stars.

Super simple to get working. I don't use any kind of standard linux on my Pi3's. I rolled my own using Yocto, but this ePaper hat was super simple to get working. Within an hour or so I had the bcm2835 library and WaveShare's C demo code up and running and displaying live values from my barn solar system. I'll definitely purchase more of these.

Always wanted an excuse to buy one. Finally thought of something to make with a raspberry pi zero w. And it's just so freaking cool! They have a really nice and well documented git repo. I was able to get their test code up and running fast with python. It's super rad that they have C sample code as well. So that's great because i would like to play with C sometime. I'm a noob with electronics and the pi pi but this was so easy to set up thanks to their documentation! I usually don't write reviews but I've just been having a blast making a little python app with this

I used it for HMI visualization, combined with an ESP8266. Partial update for quick changes in screen. Complete refresh for new screens.

Works as advertised but I had to learn how go use it, no instructions come with it! and no software!
