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/ADA5772:1.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 Adafruit's QT Py boards are a great way to make very small microcontroller projects that pack a ton of power - and now Adafruit have a way for you to add a small, colorful, and bright display to any project. Adafruit's most recent [display breakouts have come with a new feature: an 18-pin "EYE SPI" standard FPC connector with flip-top connector](https://core-electronics.com.au/search?q=eyespi). This is intended to be a sort-of "[STEMMA QT](https://learn.adafruit.com/introducing-adafruit-stemma-qt) for displays" - a way to quickly connect and extend display wiring that uses a lot of SPI pins. In this case Adafruit need a lot of SPI pins, and Adafruit want to be able to use long distances, so they go with an 18-pin 0.5mm pitch FPC. With such a slim and flexible cable, its a perfect matching for [Adafruit's QT Py boards](https://www.adafruit.com/search?q=qt+py) to make extra smol microcontroller boards with [big bold colorful displays](https://core-electronics.com.au/catalogsearch/result/?q=eyespi+display) or [power-sipping E-Ink](https://www.adafruit.com/search?q=e-ink). Don't forget you'll also want an [18-pin EYESPI FPC cable](https://core-electronics.com.au/eyespi-cable-18-pin-50mm-long-flex-pcb-fpc-a-b-type.html). And of course [one of Adafruit's EYESPI displays](https://www.adafruit.com/search?q=eyespi) too - look for the EYESPI logo on the back to know you've got one that can clip in. - **MOSI/MISO/SCK** SPI pins are connected to the default **SPI** port on the QT Py - **SDA/SCL** I2C pins are connected to the **I2C** port on the QT Py headers - some boards have a separate QT Py I2C port so keep in mind they may be separate busses. - **TFT CS** on **TX** pin - but can be re-configured/disabled by cutting a solder jumper. - **TFT DC** on **RX** pin - but can be re-configured/disabled by cutting a solder jumper. We also have 'sometimes used' pins that can be re-configured/disabled by cutting a solder jumper - **IRQ** on **A0** pin - Many of Adafruit's displays don't use the IRQ pin unless there's a touchscreen. - **Touch CS** on **A1** pin - Many of Adafruit's displays don't have a touchscreen. - **Memory CS** on **A2** pin - Only Adafruit's E-Ink displays have a separate memory SRAM chip, which you may be able to skip using on most QT Py's. - **SD Card CS** on **A3** pin - Or use for whatever you like if you aren't using the SD Card socket on of Adafruit's display breakouts. There's also two through-hole solder pads for extra pins that are often considered optional and Adafruit didn't have any more IO to spare. If you aren't using any of the 4 pins above or the I2C port, you could wire these two pins with jumper wires as you desire. - **Backlight control** - this is default on for most of Adafruit's displays, or unused on E-Ink, - **Display reset** - this is default on for most of Adafruit's displays. Sometimes its used for low-power on E-Ink. Adafruit include some header that you can solder to your QT Py. [You can also pick up an Itsy Bitsy short female header kit to make it removable but compact](https://core-electronics.com.au/short-female-header-kit-for-itsybitsy.html), you'll just need to trim down the headers to 7 pins long. - Comes as an assembled and tested PCB - For any QT Py or Xiao boards **QT Py, display and EYESPI cable are not included**. ## Technical Details Product Dimensions: 20.6mm x 17.8mm x 2.7mm / 0.8" x 0.7" x 0.1" Product Weight: 1.1g / 0.0oz ![RoHS 2 2011 65 EU Compliant](https://core-electronics.com.au/attachments/localcontent/RoHS2_2011_65_EU_7356c5574c.svg)![RoHS 2 2015 863 EU Compliant](https://core-electronics.com.au/attachments/localcontent/RoHS2_2015_863_EU_86773f57f9.svg) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/A/D/ADA5772-1.jpg)
