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/ADA5695:1.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 quickly add a nice mechanical key that also can glow any color of the rainbow. Adafruit call this the **Adafruit NeoKey BFF** - a "Best Friend Forever". When you were a kid you may have learned about the "buddy" system, well this product is kinda like that! A board that will watch your QT Py's back and give it more capabilities. This PCB is designed to fit onto the back of any QT Py or Xiao board; it can be soldered into place or use pin and socket headers to make it removable. Onboard is a Kailh socket, which means you can plug in any MX-compatible switch instead of soldering it in. You may need a little glue to keep the switch in place: hot glue or a dot of epoxy worked fine for us. Also comes with a single reverse-mount NeoPixel pointing up through the spot where many switches would have an LED to shine through. 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. The key-switch is default connected to **A3** and the NeoPixel to **A2** but there are onboard jumpers you can cut to re-configure if you desire. **QT Py is not included**. **Please note,** **each order comes with one assembled PCB and break-off header**. A mechanical switch and key cap are not included! Use any MX-compatible switch: Kailh, Gateron, etc all work! ## Technical Details ![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/ADA5695-1.jpg)
