## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA2270:1` (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/ADA2270:1.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

The "poor woman's" Raspberry Pi A+ / B+ / Pi 2 cobbler! This combo of 2x20 pin (0.1 spaced) header and socket is for Adafruit's popular [GPIO Ribbon Cable for Raspberry Pi Model A+/B+/Pi 2 (40 pins)](https://core-electronics.com.au/gpio-ribbon-cable-for-raspberry-pi-model-b-40-pins.html). It comes in two parts, a 'pin-through' socket and a male header. The socket straddles the center of a [breadboard](https://core-electronics.com.au/half-size-breadboard.html) or [Perma-Proto](https://core-electronics.com.au/adafruit-perma-proto-half-sized-breadboard-pcb-single.html) and then header plugs into the top of the socket. Since IDC cables are so standard, but a royal pain to use with breadboards, this is a good and cheap hack for prototyping

Works best when soldered in place. Adafruit have used these to prototype on a solderless breadboard but some customers report their breadboards don't play nice with the shorter pins so your mileage may vary.

**Each order comes with one socket and one header.** Breadboard, Perma Proto and IDC cable not included!
