“In general, it is an excellent display. Much bigger than pHAT. The only drawback is slow refresh (about 40 sec. on Pi zero W) so wHAT is not a perfect solution to every project. But for projects like calendar, weather forecast, info/alert panel, etc it is great.”
“I wanted something bigger than Inky pHAT, so when I saw new Inky I bought it immediately. The display is great, so is the visibility of the screen. Demo code shows how to draw dithered photos, which is great. I used it my weather forecast script. Results are excellent. However, the refresh rate is slow. The whole process of drawing new screen lasts about 40 seconds (demo script + 400x300 png, pi zero w), but the flickering part is just 10 seconds. So for the projects with a few redraws per hour/day, it is perfect. Otherwise, it is way too slow. Anyway, I'm really happy that I have it.”
