Did you ever managed to get this working? @Anthuzad
Yes.. I used the Sleepy PI 2 Hat. There’s still current draw from the sleepy pi but it is a lot less. I only did this for one frame because they cost more than a RPI Zero 2 W. I used good old USB inline power switches for the rest of them. The next frame I am going to drill a small hole in the side of the frame and 3D print a button that will extend to inside the frame and push a micro USB button.
So can anyone in here confirm that they have the inky impression 13.3” 2025 model working with any of the witty pi models? It looks like there are gpio conflicts but based on this thread I’m not sure that is correct. Anu help would be appreciated
