## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE08566:1` (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/CE08566:1.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

Most stackable headers are made with thin, stamped-metal - resulting in flimsy pins. Not these headers! These are made with 50% thicker pins, making them substantially stronger, less prone to bending, and an all-around pleasure to use.

These 0.1" stackable header strips are commonly used as low-cost connectors for custom-made cables or perforated [prototyping PCBs](https://core-electronics.com.au/makerverse/prototyping.html). This 20-pin header happens to be the perfect size to suit a [Raspberry Pi Pico](https://core-electronics.com.au/raspberry-pi-pico-soldered-headers.html) so you won't have to cut it down to size which can leave sharp, unsightly edges.

If you are looking for matching headers in another style, see our [20-pin female headers](https://core-electronics.com.au/header-20-pin-female-0-1-10-pieces.html) and [40-pin cuttable male headers](https://core-electronics.com.au/male-pin-header-2-54mm-1x40.html). Or we have even more varieties in our [headers category](https://core-electronics.com.au/connectors-sockets/headers.html).
