2.13inch E-Paper HAT+ for Raspberry Pi 5 4B 3B+ 3B Zero W Zero 2 W Jetson Nano, E-Ink Display 250x122 SPI Interface HAT+ Standard with Pwnagotchi Tutorial Support Partial Refresh

First of all, this is pretty much the best e-paper display for the Pi02 W+. Response time is fast, image quality is great, and the whole thing is solid. The only thing to note is that this version does NOT include the onboard RTC battery as depicted in the product photos. This version has a header for an external battery (I forget the connector type, but it's the same as most laptop CMOS batteries). While this wasn't an issue in my implementations it's something to consider if you're planning to build something like a Slimagotchi with minimal hangy-offy bits.

First and foremost this little screen isn’t a replacement for a monitor. That’s not what ePaper is good at (yet). But if you want to be able to look at your Pi and see some needed detail on a headless setup, this would be really good. Things that don’t change often like IP address and similar types of data that would be nice to just look at without needed to connect a monitor.Setup was reasonably straightforward, though I needed to dismount the lid of my heat sink case to use it. I don’t consider that to be a failing of the product as most Pi’s are run bare, so there isn’t really a call for an extension header, but with the number of people that like to use cases or heat sinks on specific chips it would be a value add in the future or at least something else to consider based on which Pi model you will put this hat on.All of my concerns aside, this is a neat little piece of kit and will add a lot to your digital gadgeteering.

I'm a big fan of using E-ink / E-paper displays in my projects. They're perfect for displaying important information while requiring no power to maintain the display's contents. This interfaces easily with my various RPi devices, including the Zero devices. It was easy to find and install the needed libraries and I had it integrated in a matter of minutes. If you haven't used E-paper displays, this is the perfect device to get started with!

The Waveshare 2.13" E-Paper HAT is a fantastic addition to any Raspberry Pi project that requires a low-power, high-contrast display. I've been using it with my Raspberry Pi Zero 2 W, and I'm impressed with its performance and versatility. The e-paper display offers several advantages over traditional LCD screens. First, it's incredibly energy-efficient, making it ideal for battery-powered projects. Second, the display has excellent contrast and viewing angles, making it easy to read even in bright sunlight. And third, the display can hold an image indefinitely without consuming any power, which is perfect for displaying static information. I recommend it!

The link to the example code is in the description, it was not obvious to me at first and unfortunately it is not a clickable link. I found I had to copy and then paste it into the address bar in a new tab. If you have trouble or can’t find it, go to the Waveshare Wiki and search for “2.13inch_e-Paper_HAT+”.After following the directions under the “Working With Raspberry Pi” section I enabled the SPI interface and then installed all the C libraries. The C code compiled without any trouble and then ran without any issues. I then was able to follow the instructions to install all the Python libraries and was also able to run the Python code without any issues. Both languages have support for partial display refresh, a feature I plan to use. I also found the display to be nice and sharp.I did have a try at setting up my Pizero as a pwnagotchi but I was unable to get anything to work. I didn’t want to devote more time to getting something running just as a test since I was not interested in dedicating this display and Pizero to be a permanent pwnagotchi.Overall installing the example code was easy and quick. In about 30 minutes I had a functioning display. I would recommend this Waveshare ePaper display to anyone who is looking for such a display for their Raspberry Pi Zero.

This has been a good addition to my Pi 5. It seems well made and once I found the code tutorials and pin assignments with connectly easily. It works pretty well and is going to made the perfect interface for my current project. The display is sharp and clear for E-Ink and the response time is quick. At this point I can't find anything I am unhappy with.

E-ink displays are great. This one is perfect in size to pair with a pi zero or zero 2. I hooked it up with a pi zero 2 w and use this to display the network status. I think next I'll figure out how to make it show qr codes. But it's lots of fun!
