# GPIO Female Socket Riser Header - 2x2 4-pin

**Type:** Product page · **SKU:** ADA4855 · **Brand:** [Adafruit](https://core-electronics.com.au/brands/adafruit-australia)
**Page:** https://core-electronics.com.au/gpio-female-socket-riser-header-2x2-4-pin.html ([markdown](https://core-electronics.com.au/gpio-female-socket-riser-header-2x2-4-pin.html.md))

This 0.1mm pitch 2x2 Female Header is the perfect boost to use with boards that use the 4-pin 'PoE' header on the Raspberry Pi 3 and 4, like the Raspberry Pi PoE HAT! It's a great pairing to the 2x20 socket riser header to get a full lift.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA4855:1` (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/ADA4855:1.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)
