This PCB looks just like a round E-Ink breakout but has permanently affixed M3 standoffs that act as mechanical and electrical connections. ## Pricing - **Price:** $40.40 (inc GST) — $36.73 AUD, exc GST - **Quantity discounts:** 10+ $35.63 (exc GST) · 50+ $34.89 (exc GST) ## Availability & dispatch - Out of stock — the product page offers email notification when it returns. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA4869:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA4869:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description Extend and expand your Circuit Playground projects with a bolt-on E-Ink Gizmo that lets you add a lovely tri-color e-Ink display in a sturdy and reliable fashion. This PCB looks just like a round E-Ink breakout but has permanently affixed M3 standoffs that act as mechanical and electrical connections. 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! Once attached you'll get a 1.54" 200x200 display (black and red ink pixels and a white-ish background), two 3-pin STEMMA connectors for [attaching NeoPixel strips](https://core-electronics.com.au/adafruit-neopixel-led-strip-with-3-pin-jst-connector-60-led-meter-0-5-meter.html) or [servos](https://core-electronics.com.au/micro-servo-with-3-pin-jst-cable-stemma-connector-compatible.html), and a Class D audio amplifier with [a Molex PicoBlade connector that can plug one of Adafruit's lil speakers](https://core-electronics.com.au/search/?q=moled%20speaker). Using Adafruit's CircuitPython or Arduino library, you can create a 'frame buffer' with what pixels you want to have activated and then write that out to the display. **[The library Adafruit 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). This E-Ink breakout does not contain an extra SRAM chip (not enough pins are available) so you'll need ~7K of SRAM to spare for a display buffer, the CPX has 32KB and the CPB has 256KB, so there's plenty of RAM. This is a great companion for Adafruit's Circuit Playground Express or Bluefruit boards thanks to their fast SPI hardware speeds and plenty of RAM, and works in Arduino and CircuitPython. If you're using this with Circuit Playground Express and CircuitPython, you won't be able to do a lot because there isn't a ton of memory - mostly just displaying the REPL and maybe running an image slideshow. For CircuitPython use, the Bluefruit is recommended and works really great! **You cannot use it with the Circuit Playground Classic in Arduino, there's not enough RAM!** Comes with a PCB that has pre-soldered standoffs attached, and 12x M3 screws for attachment. Fits all Circuit Playgrounds, but like Adafruit mentioned earlier, the Express and Bluefruit are recommended. ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/4/8/4869-01.jpg)
