Review on 📺 1.54 Inch E-Paper Screen Display Module | Resolution 200x200 | 3.3v | E-Ink Electronic Display with Embedded Controller | SPI Interface | Partial Refresh Support | Raspberry Pi/Arduino/Nucleo/Jetson Nano Compatibility by John Goerge

I have a 7.5 inch display. The product only worked once. I used the example code provided and it didn't work until I got my hands on the device. I'm guessing he moved the plug and drew a "J" but that's about it. I reinstalled the connectors and it still doesn't work. That's a waste of money. Potentially it could be a great product but to make it happen. It has to work first. I wanted it to work but I don't have time to troubleshoot their hardware.
