Review on 📺 2.7inch E-Ink Display HAT E-Paper Screen LCD Module 264x176 Resolution SPI Interface for Raspberry Pi/Arduino/STM32/Jetson Nano, with Embedded Controller by Walter Velasquez

The device does not work via Arduino (with Waveshare shield) or on RPi, using Waveshare's native readme and Git project only results in the screen showing C- APIs persistent or empty. I'm very upset that it didn't work, I was looking forward to a good e-paper ad. Edit: I found that the device actually works with python bindings. So while only 1/3 of the demos work correctly for this, I can at least rule out that the hardware is bad. 3/5 stars.
