## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA3907:1` (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/ADA3907:1.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

Here's a snazzy accessory for your Raspberry Pi Zero or Zero W, a color-coded 2x20 header! This **Color Coded Header** takes the mystery out of your Raspberry Pi's 2x20 pinout. No longer will you stare in confusion at all 40 pins, trying to count out which one you want to plug your wires into.

Peep this handy color coding:

- Red = 5V
- Yellow = 3V
- Black = GND
- Blue = Do Not Connect
- Green = GPIO

Connecing to your Pi Zero requires a bit of soldering, but if you're looking for an alternative, try the [solderless GPIO Hammer Headers](https://core-electronics.com.au/gpio-hammer-headers-solderless-raspberry-pi-connectors-male-female-installation-jig.html)!

**Please note:** only the Pi Zero and Zero W come without a header pre-soldered. You won't be able to use this with the Pi 2, 3 or Zero WH as those Pi's have pre-attached header pins.
