Waveshare 1.54 Inch E-Paper Display Module (B) V2.200 x 200 Resolution 3.3 V/5 V E-Ink Electronic Screen with Embedded Controller, Red Black White Three-Color for Raspberry Pi/Jetson

Easy to wire up and test using the example code available online, but the red colour is very weak and disappointing. Returned for a refund. Customer service did at least try to suggest a few things but I think this must be a faulty unit.

This product is a bare e-ink display module. It comes in just the module and the connection cable, nothing more nor less. I don't like it doesn't come with any short/long/simple printed documentation or manual. So customer needs to research the code or testing procedure online instead.E-Ink display is good for its low power consumption and great for static information or "rarely" change/update. It uses simple SPI interface which is easily worked out with Arduino or Raspberry Pi/Pico etc. It will be great if it offers more documentation or tutorial to those beginner customers.

Waveshare, by and large, is the only name in e-paper development boards targeted at the "simpler" microcontroller development platforms like Arduino and ESP-IDF. So, odds are if you've used any, you've used their stuff.This is probably the sixth or seventh variant of a Waveshare display I've bought and its the same excellent quality I would've expected from any of them. The board supports normal 3 or 4-wire SPI connectivity, and all of the common Arduino and IDF libraries support these out-of-the-box. So, really, its just a matter of wiring it up and running a little bit of sample code to get going with them.The one "weird" thing with the one I received -- out of probably twenty Waveshare displays I've bought over the years, this was the first one to come without a test image on it. I kind of suspect that may mean I was shipped a returned item and not a new one, but I suppose its possible they've stopped doing that.One thing to note, for people wanting to build a project using e-paper -- these three color displays are *extremely* slow to update. Like 10-20x slower than the 2-color black-and-white versions. So, if you aren't pretty sure you need the accent color (generally red or yellow), stick with the black-and-white. The end-user experience of these is pretty mediocre because of the 10-15 seconds an update takes, flashing over and over during the entire time. I only use these when its something that needs to persist a long time and its unlikely someone is looking at it as it updates.There are some experimental code examples that use dramatically more aggressive refresh timings on these that can make it faster, as Waveshare definitely uses extremely conservative settings, but they often don't work properly or leave ghosting.Regardless, you can't go wrong with their modules.

The media could not be loaded.  La taille, l'épaisseur et la qualité d'affichage sont au rendez-vous. De même le site web est une très bonne source d'information qui permet de faire très rapidement le câblage et il y a aussi pas mal d'exemple de code et des libs pour Arduino, Raspberry Pi et autres.Le seul gros problème qui lui fait perdre 2 étoiles est la vitesse de rafraichissement. Bien sûr on est pas sur de l'OLED mais un simple display(image_noire, image_rouge) prend plus de 15 secondes.

I'm surprised! The product arrived 1 day earlier.The quality is fair for the price, no complains.On the Waveshare website there are some examples for beginners like me.

Dopo aver provato svariate volte (seguendo passo passo la wiki del produttore) a collegare lo schermo sia al raspberry pi3b che al pi3b+ che ad un arduino mega 2560 mi sono convinto che fosse lo schermo ad essere difettoso. Ne ho quindi comprato un altro ed ho avuto lo stesso identico problema. Sconsigli vivamente l'acquisto.
