Adafruit 2.13 250x122 Tri-Color eInk / ePaper Display with SRAM - SSD1680 Driver

Finally, easy e-paper has arrived for microcontrollers! This breakout board makes it super simple to add a tri-color eInk display. You've probably seen e-readers like the Kindle or Nook. Their electronic paper displays keep the image even when the power's off, offer high contrast, and are easily readable in daylight - just like real printed paper. We've loved these displays for ages, but there were no breakouts for makers. So, we made our own! This 2.13-inch display has red, black, and white colors, with 250x122 black and red ink pixels on a white-ish background. With our CircuitPython or Arduino libraries, you can create a 'frame buffer' and write it to the display. However, the pixel data can be too large for many microcontroller memories. That's why we added a small SRAM chip on the back. It shares the SPI port with the eInk display, needing only one extra pin. No more frame - buffering hassle! The library does all the work, and you can interface with it like an Adafruit_GFX compatible display. For ultra - low power use, you can shut down the power to the SRAM, MicroSD, and display via the onboard 3.3V regulator's Enable pin. There's also a MicroSD socket for storing images and text files. It's 3 or 5V logic safe, suitable for all microcontrollers. The product comes assembled and tested with some header. You'll need a soldering iron to attach the header for breadboarding or your project.

Using this Adafruit eInk display is a piece of cake. First, if you're using it for breadboarding or want to install it in your project, you'll need to use a soldering iron to attach the provided header. Once that's done, connect it to your microcontroller. You can use our CircuitPython or Arduino libraries to create a 'frame buffer' of the pixels you want to show. Thanks to the SRAM chip on the back, you don't have to worry about running out of memory in your microcontroller. Just set up what you want to display in the SRAM, and when you're ready, the library will move the data to the eInk display. If you want to save power, you can use the Enable pin on the 3.3V regulator to turn off the power to the SRAM, MicroSD, and display. You can store all kinds of stuff like images and text files on the MicroSD card for display. Remember, this display is 3 or 5V logic safe, so it'll work with any microcontroller. As for maintenance, keep it away from extreme temperatures and moisture. If there are any issues, check your connections and make sure the libraries are up - to - date.
