## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA2222:1` (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/ADA2222:1.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

Connect your own PCB to a Raspberry Pi with this normal-height female header. The female header part is about 8.5mm tall, good for small HATs that do not to clear the USB/Ethernet jacks. This header has 3mm of pins, compared with Adafruit's [stacking version](https://core-electronics.com.au/gpio-header-for-raspberry-pi-b-extra-long-2x20-female-header.html) which is the same base height but has 10mm header pins instead. With 3mm you don't have to cut the really long pins, so its ideal for basic Pi HAT design

You'll get one header per order.
