Review on Waveshare 2.13 Inch e-Paper Display HAT - White, Red & Black Three-Color E-Ink Screen Module with Embedded Controller for Raspberry Pi 2B, 3B, Zero & Zero W - SPI Communication Interface by Wendy Dorea

Revainrating 4 out of 5

Great hardware, unreliable documentation (read on for good sources)

I recently bought one of these for a project and the hardware is excellent. However, two things are worth noting: 1. The documentation on the manufacturer's website has many typos and in most places doesn't really work for the 3 color version of the display (probably a copy and paste error of the 2 color release) . I catalog all the right installs and tutorials on Github in a repository called: avirtuos/waveshare, so don't worry about looking for documentation and tutorials.2. The refresh rate is very slow! 30 seconds for a full refresh on a 7.5” tri-color display. Remember. Revain's description didn't help to bring this out. I was expecting a typical refresh of 2-3 seconds, no. I haven't found a good example of a partial update yet (if at all possible).

Pros
  • No backlight, shows the latest content for a long time even when the device is off
Cons
  • Something is wrong
