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!\u003c\/p\u003e\u003cp\u003eWe've liked these displays for a long time, and they're just about Feather sized, so wouldn't a custom e-paper FeatherWing make a ton of sense?\u003cstrong\u003e This 'Wing is tested to work with \u003cem\u003eall\u003c\/em\u003e of our Feathers\u003c\/strong\u003e, from the ESP8266 to the M0. It has built-in memory buffering so it can work with chips as small as the '32u4 and '328. It \u003cem\u003edoes\u003c\/em\u003e use a lot of pins: the 3 SPI pins, and up to 4 control pins to manage the SD card slot and SRAM.\u003c\/p\u003e\u003cp\u003eThe FeatherWing sports a \u003cstrong\u003e2.13\" tri-color (red, black, and white) display\u003c\/strong\u003e. It has 250x122\u003cstrong\u003e \u003c\/strong\u003eblack and red ink pixels and a white-ish background. We used to stock a version of a 2.13\" tricolor E-Ink with a lower-resolution display,\u003cstrong\u003e this version is 250x122 pixels instead of 212x104 pixels and uses a different chipset (SSD1680) so code will need to be recompiled.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eUsing 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 colors = 7.5 KBytes. Which won't fit into many microcontroller memories. Heck, even if you do have 32KB of RAM, why waste 8KB?\u003cstrong\u003e \u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSo we did you a favor and tossed a small SRAM chip on the back.\u003c\/strong\u003e This chip shares the SPI port the eInk display uses, so you only need one extra pin. And, no more frame-buffering! \u003cstrong\u003eYou 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\u003c\/strong\u003e, you can just interface with it as if it were an Adafruit_GFX compatible display.\u003c\/p\u003e\u003cp\u003eWe even tossed on a MicroSD socket so you can store images, text files, whatever you like to display. Comes assembled and tested with socket headers that you can plug your Feather right into, no soldering required!\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cdiv class=\"row\"\u003e \u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\n\u003cul\u003e\n\u003cli\u003eDimensions (excluding mounting holes): 61.5mm x 31.4mm x 6.6mm\u003c\/li\u003e\n\u003cli\u003eDriver chip is the SSD1680\u003c\/li\u003e\n\u003cli\u003ePanel variant is RW\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eProduct Weight: 14.5g \/ 0.5oz \u003c\/p\u003e\n\u003c\/div\u003e \u003c\/div\u003e\n\u003cul id=\"product-files\"\u003e \u003c\/ul\u003e \u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e \u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":43493259214925,"sku":"pco1787258241249","price":19.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/1182\/8301\/files\/adafruit-213-hd-tri-colour-eink-epaper-display-featherwing-250x122-rw-panel-with_1.jpg?v=1787258246","url":"https:\/\/www.grandorchard.shop\/products\/adafruit-213-hd-tri-colour-eink-epaper-display-featherwing-250x122-rw-panel-with-ssd1680","provider":"My Store","version":"1.0","type":"link"}
