## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA2223:1` (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/ADA2223:1.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 B+ and stack on top with this normal-height female header with extra long pins. 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 extra long 10mm pins, compared with Adafruit's [plain version](https://core-electronics.com.au/gpio-header-for-raspberry-pi-b-2x20-female-header.html) which is the same base height but has 3mm header pins instead. With 10mm you can have a HAT that has extra pins to stack another HAT on top!

You'll get one header per order.

**Note: The Raspberry Pi Model A+, Raspberry Pi 2 and Raspberry Pi 3, Raspberry Pi 4 are also compatible with this product!**
