Waveshare 7.5inch E-Ink Display HAT Compatible with Raspberry Pi 5/4B/3B/Zero/Zero W/Zero 2W/Pico/Pico W/Pico WH, 800×480 Resolution SPI Interface

If you know what you're doing in Home Assistant and ESPhome then you can put in a little work to make a custom display like this that will communicate many things without getting in your face. That's why I like these screens. A subtle way to share info in the home.

Due to amazon's stance on linking to external sites, this review _can't_ post actual useful information (like the technical spec), but I will try my best.These screens are great. At 1-bit color depth (black and white) with a 800x480 display resolution, you can print a fair amount of content on them. The included ribbon and SPI interface board is amazing and makes things basically plug-and-play. Now, this is also in the maker space, so it isn't a generic thing you can plug in to any old computer. You have to have some idea of what they are and how to use them (but, as a hardware newbie myself, I was able to find the necessary information to get it up and running on a Raspberry Pi Pico (RP2040) within a week.From my perspective, the hardest part of using this product is literally wiring it to the micro-controller correctly; after that, it is just sending it commands, and data.The screen is about .8mm thick, and it is made of glass, so you will want to be careful with it. It appears to come with a protective film over the front, and they suggest that if you are using it for development purposes, you reinforce the back as well. I did this by taping it to a wooden clipboard, giving it a rigid surface to be flat against.The fact that this screen runs at 3.3v is great, you won't need a boost converter or any additional hardware to be able to run with most micro-controllers or Raspberry Pi units. I wish that some of their more expensive displays could also operate on 3.3v (instead of 5v, which a lot of them require).This screen supports true partial drawing/ refreshing, which is very nice; though does take a bit of time to get used to as you specify the banks that are going to be drawn and refreshed with the command, instead of the raw pixels you want to modify (in this case, a bank is 8 pixels wide by 1 pixel tall).Full screen refresh appears to take around 5 seconds, so it isn't the fastest out there. It is also worth noting that they strongly suggest that you don't leave the display powered up at all times. The main loop flow diagram they have shows powering on, initializing the settings, drawing the content to the screen, and then power off followed by deep sleeping the display. So long as you don't disconnect the screen from power, you can go through a truncated restart process where you just re-send the settings and can draw right afterwards. This saves a little time, but the entire boot sequence really doesn't take very long (at least in comparison to a redraw).Waveshare has a website with a wiki which contains all the technical specifications for their various displays, and they also have a github with examples on a number of embedded devices for each of their screens. I can't post direct links, but a quick web search should be able to turn those up.

The media could not be loaded. This is my first e-ink display, i'm impressed so far. This has been fun to play with and start a project with. Documentation feels a little scattered, initially I struggled to get everything working. I was initially using the hat connection on my raspberry pi, when that wasn't working I switch to using the direct wire connection. I'm not sure if it was the hat connection or not, I need to test that again, but with direct pins it's working.I have tested both the c and python libraries provided by waveshare. Make sure to get the correct version. The sample files run through a lot of the features, drawing images, shapes and partial refresh.Try some things out and you can get a feel for what is possible.

The one thing I wish I'd paid more attention to was the reviews saying how fragile this is. The connector on the display itself is indeed incredibly fragile and barely attached to the display at all. It can't be inserted into the provided e-Paper adapter without bending and pushing and the slightest pressure has been enough to tear it away from the screen entirely.I suspect I may have gotten a bad unit since even though I did manage to get the connector inserted once without apparent damage it didn't respond to commands. I was trying to re-seat the connector when it tore, which I didn't realize even happened until I had already gotten the connector back in place.I'll definitely not be buying another given how fragile it is, I'll just cut my losses and try to find another comparable product with hopefully a sturdier and easier to insert connector..

Waveshare 7.5inch E-Ink Display HAT for Raspberry Pi 640x384 Black White Two-color Display Screen SPI No Backlight Ultra Low ConsumptionCurrent user of the 7.5 inch screen. Screen refresh is adequate, it will flash entire screen while displaying though (usually alternating 2 between black and white). It may be possible to implement partial refresh of the screen, however I have not had any luck doing so ( or finding sources ).Here is a list of source code in order of most responsive to least on a PI W0:BCM2835: By far the fastest source code to use, likely due to direct access to GPIO device memory /dev/mem. Typically as soon as I invoke my executable, the screen is responding within the first couple of seconds.WiringPi: Typically as soon as a run the executable there is a notable delay of a few seconds before the screen is responding. Still quick, but not nearly as quick as the BCM2835 based source code.Python: The Python source code is by far the slowest with an extremely noticeable delay before the screen is responding. The only time I've seen Python work quickly on the E-Ink display is with smaller, less intensive displays.Screen is great if you don't mind the flashing refresh, I'll update later if I find a way to implement partial refresh, or if the manufacture let's me know of any new source code implementing that ability.

Hooked this up to a Raspberry Pi as an e-paper weather display. It's worked flawlessly now for months!

Ace product, worked flawlessly. Everything was easy to setup and use.

This worked great for me and what I wanted to use it for, until one day I hastily moved it and made a small tear in the ribbon cable. The cable is permanently attached to the screen, so there's no way to replace it.Be careful!

Byggde en dashboard i en IKEA Ribba fotoram kopplad mot Home Assistant och ESP Home enligt andras ideer och kod online. Har fungerat felfritt i ett år!

Works as expected. Thank you.

Habe mir das Display gekauft und damit ein esp32 Projekt nach heise+ Anleitung umgesetzt.Klappt problemlos.

The media could not be loaded. Un poquito caro pero la entrega inmediata lo merece.Funciona perfectamente y me encanta el aspecto que tiene para el proyecto en el que lo he usado.Si alguien es fan de Portal, lo recomiendo!!!Busca en github wuspy/portal_calendar no te defraudará

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.
