## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA1986:1` (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/ADA1986:1.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

Oof - [you got a Raspberry Pi Model](https://www.adafruit.com/categories/105) [A+](https://core-electronics.com.au/raspberry-pi-model-a-256mb-ram-9724.html) or [B+](https://core-electronics.com.au/raspberry-pi-model-b-512mb-ram-9249.html) that you want to have work with some old kit or plate or breakout or something and it uses the classic 26-pinout. Very frustrating, it is...unless you have this ingenious 'downgrade' GPIO cable. It has a 40-pin socket on one end, but only the first 26 pins have a cable and the other end matches any sort of Cobbler or PermaPi or what-have-you.

Cable is 6" long, and pin #1 is marked with a white wire. **This cable is not compatible with the Raspberry Pi Model A or B** - It's for the A+ and B+ only!

Available in slimming Adafruit Black - pin #1 is marked with a white stripe!

**Note: The Raspberry Pi Model A+, Raspberry Pi 2 and Raspberry Pi 3 are also compatible with this product!**
