- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA4156:1.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.

## Description

Female header is like the duct tape of electronics. It's great for connecting things together, soldering to perf-boards, sockets for wires or break-away header, etc. Adafruit go through these real fast, and thought that given how handy they are, we'd offer them in a pack of five!

Each pack contains five blue **20-pin 0.1" pitch female headers**. These are a little extra special in that the plastic holding the pins together is made of blue plastic instead of classic black.

You can cut these down to different sizes fairly easily with diagonal cutters to cut in between pins.

[Adafruit have a ton of different types, sizes, and shape headers in the store - check'em out!](https://www.adafruit.com/categories/154)
