# Adafruit 2.13" 250x122 Quad-Color eInk ## Overview ![front view of the board](https://cdn-learn.adafruit.com/assets/assets/000/138/558/medium800/adafruit_products_6366-01.jpg?1753362716 ) Easy e-paper finally comes to microcontrollers with this breakout that's designed to make it a breeze to add a quad-color eInk display. Chances are you've seen one of those new-fangled 'e-readers' like the Kindle or Nook. They have gigantic electronic paper 'static' displays - that means the image stays on the display even when power is completely disconnected. The image is also high contrast and very daylight readable. It really does look just like printed paper! ![back view of the board](https://cdn-learn.adafruit.com/assets/assets/000/138/559/medium800/adafruit_products_6366-02.jpg?1753362771 ) We've liked these displays for a long time, but breakouts were never designed for makers to use. Finally, we decided to make our own! This is a **2.13" quad-color (red, black, yellow and white) display**. It has 250x122 black, red and yellow ink pixels and a white-ish background. It uses the JD79661 chipset, so make sure whatever firmware code you are planning to use has support for it. Using our CircuitPython or Arduino libraries, you can create a 'frame buffer' with what pixels you want to have activated and then write that out to the display. Most simple breakouts leave it at that. But if you do the math, 250 x 122 pixels x 2 bits = 7.5 KBytes. Which won't fit into many microcontroller memories. Heck, even if you do have 32KB of RAM, why waste 8KB? ![lines on the display](https://cdn-learn.adafruit.com/assets/assets/000/138/560/medium800/adafruit_products_6366-06.jpg?1753362811 ) **So we did you a favor and tossed a small SRAM chip on the back.** This chip shares the SPI port the eInk display uses, so you only need one extra pin. And, no more frame-buffering! **You can use the SRAM to set up whatever you want to display, then shuffle data from SRAM to eInk when you're ready. [The library we wrote does all the work for you](https://github.com/adafruit/Adafruit_EPD)**[, you can just interface with it as if it were an Adafruit\_GFX compatible display](https://github.com/adafruit/Adafruit_EPD). ![four squares in the four colors on the display](https://cdn-learn.adafruit.com/assets/assets/000/138/561/medium800/adafruit_products_6366-05.jpg?1753362857 ) We even tossed on a MicroSD socket so you can store images, text files, whatever you like to display. Everything is 3 or 5V logic safe so you can use it with any and all microcontrollers. For ultra-low power usages, the onboard 3.3V regulator has the Enable pin brought out so you can shut down the power to the SRAM, MicroSD, and display. ![quadcolor text on the display](https://cdn-learn.adafruit.com/assets/assets/000/138/562/medium800/adafruit_products_6366-04.jpg?1753362883 ) This display breakout also features an 18-pin "EYE SPI" standard FPC connector with flip-top connector. [You can use an 18-pin 0.5mm pitch FPC cable](https://www.adafruit.com/product/5239) to connect to all the GPIO pins, for when you want to skip the soldering. Comes assembled and tested, with some header. You'll need a soldering iron to attach the header for breadboarding or installing it into your project. - [Next Page](https://learn.adafruit.com/adafruit-2-13-250x122-quad-color-eink/pinouts.md) ## Primary Products ### Adafruit 2.13" 250x122 Quad-Color eInk / ePaper Display w/ SRAM [Adafruit 2.13" 250x122 Quad-Color eInk / ePaper Display w/ SRAM](https://www.adafruit.com/product/6366) Easy e-paper finally comes to microcontrollers, with this breakout that's designed to make it a breeze to add a quad-color eInk display.
