To only did the existing documentation fail me, but that experience is shared among other reviewers on here and YouTube alike. These displays are not worth it unless you are comfortable with very low-level coding and effectively partially writing the software for your use case. Would not recommend for a hobbyist like myself.

Das Produkt selber ... damit bin ich voll und ganz zufrieden.Die Installationsbeschreibung bei Waveshare ist einfach ... war nicht alles 100%ig wie beschrieben bei mir, aber das ist vermutlich auf die aktuelle Raspberry Pi OS-Version zurückzuführen.Das Display läuft ohne Probleme.Was mich persönlich sehr stört, ich kann für die verwendete Library in Python keine ordentliche Beschreibung finden ... kein Befehlssatz für die Lib ... nur Installationsanleitungen. Wäre schön, wenn hier nachgebessert würde. Deshalb auch nur 4/5 Sternen.Im Moment setze ich das Display als Uhr ein ... implementiere Stück für Stück Funktionen, die dann das fertige Display für den eigentlich geplanten Einsatz "vorbereiten". Als Uhr soll es nicht eingesetzt werden! ;) Theoretisch würde es als Uhr auch nur ca. 3 Jahre halten. ... wäre also Unsinn.

I love it. My only complaint is that you can't do partial fast refreshes from the included python library.Regardless it's currently acting as a clock attached to my pi4 and I just love the way it looks. And I plan to make it a data dashboard soon.I previously bought another one that is graphing my savings account with an adafruit timer 5110 and a battery. No issues with either.

I was able to set up and get running with my raspberry in to time. I found extensive documentation and sample code at the Waveshare wiki. The e-Paper display looks great!

I got it working first with it plugged directly onto the header because I could not find the pinouts.Now that I have found them I wanted to share. (see images)Color : Pin NumberRed : 1 (or 17) : 3.3vBlack : 6 (or 9,14,25,30,34,39) : groundwhite : 11purple : 18blue : 19green : 22yellow : 23orange : 24Red is 3.3v and can alternately go on pin 17Black is ground and can go on any of these pins: 6, 9, 14, 25, 30, 34, 39

This fits perfectly on a raspberry pi, and after some trouble setting it up it can be used pretty easily with Python. The refresh rate is very slow (>6 seconds) but that was expected buying the product. Overall it performs very well for the specs.
