You can find this unit and other IT8951-based driver boards for it on a few different places/in different catalogs but Waveshare's easy and the price seems OK.
The ED133UT2 is a Carta 1200 display. The latest Carta gen is the 1250, but AIUI it's only relevant for color displays with the change being a thinner film that allow plastic color filters to be closer to the ink to improve contrast. I think the current greyscale 13.3" offered by E Ink's direct shop for $449 sans driver is still a 1200 - at least many vendors list VB3300-NCB as just an alternate name for the ED133UT2. The Carta range of displays are well-known from Amazon's Kindle and many other reader products, so my newspaper is basically a big honking DIY Kindle.
They also offer a 10.3" panel with even higher resolution for half the price of the 13.3" that's supported by the same controller and should be fantastic for all sorts of home dashboards.
While cobbling together my project I was really tempted to go custom PCB with the ESP and the ITE controller on one board. Looks like this eschews the seperate controller entirely and instead uses ESP32 PSRAM for the framebuffer and has the driving waveforms embedded in the MCU firmware etc. Very neat, also one further level of "go deeper", would love to try one!
This seems to be pretty common with E Ink displays unfortunately (you hear the same about many commercial ebook readers). At least the larger ones are more or less all from the same manufacturer (E Ink). I don't know if there is binning going on and Amazon gets better batches than Waveshare does ...
Direct sunlight can also be a big problem for this display tech, so I'm intentionally hanging it on a wall facing away from the most intense daytime sunlight I get.
I saw something like this a couple of years ago and wanted to do it myself. However the cost was relatively unattainable at the time, I'm glad to see it is getting more affordable!
It's this product, which is built around a ED133UT2 panel by E Ink: https://www.waveshare.com/product/displays/e-paper/epaper-1/...
