## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA5781:1` (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/ADA5781:1.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)

## Description

With most of Adafruit's dev boards, sensors and feathers now sporting [plug-and-play stemma QT ports](https://learn.adafruit.com/search?q=stemma%2520qt) it can be very fast to put together projects with half a dozen boards snapped together. But that ease of use has one downside: now you don't have a breadboard as a mechanical substrate... which is why Adafruit created this nifty swirly grid design to allow for easy mounting of various small microcontroller and sensor boards.

The grid is made out of an 'aluminum PCB' - Adafruit have that in quotes because while technically it is made with a PCB process for single-sided aluminum-core PCBs, there's no actual copper on here, its just the aluminum backing, and then black soldermask with silkscreen. The aluminum is conductive both electrically and thermally - so watch out if you are using metal screws to attach stuff. Unless, that is, you want to turn the whole thing into a ground plane in which case: go for it.

Each square is 0.6" x 0.6" and there's holes or slots every 0.2 inches. With the various dots and dashes you can pretty much make anything on a 0.1" grid fit. Each drill hole is 0.1" / 2.54mm diameter, the slots are 0.11" x 0.3" (2.75 x 7.5mm) And if that's not good enough, the aluminum is easy to cut/drill/machine/bend if you need more customization.

**This one is 10x10 'blocks', so 6" x 6" in size or about 150x150mm**
