## Pricing

- **Price:** $7.50 (inc GST) — $6.82 AUD, exc GST
- **Quantity discounts:** 10+ $6.55 (exc GST) · 25+ $6.35 (exc GST)

## Availability & dispatch

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE08424:1` (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/CE08424:1.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

The "Fake HAT" is a 2x20 way female connector with long pins soldered to a board with a Raspberry Pi HAT compliant CAT24C32 (32kbit EEPROM) on I2C address 0x50.

It's designed to be used for quick testing of GPIO configuration (direction/mode/etc.), kernel overlays and storing configuration files without having the real hardware connected to the [Raspberry Pi](https://core-electronics.com.au/catalog/product/view/sku/CE0642)!

- Emulate a Raspberry Pi HAT to test software!
- Develop EEPROM contents for a compliant Raspberry Pi HAT!
- Setup GPIO pins, overlays etc for breadboard projects!

The EEPROM connects to the Raspberry Pi GPIO ID\_SD (physical pin 27) and ID\_SC (physical pin 28) and GND/3v3.

[For guidance on using the Fake HAT, 8086 advise checking this forum thread](https://www.raspberrypi.org/forums/viewtopic.php?t=108134).

**Please Note:**

- PCB colour may vary
- Raspberry Pi and [heatsinks](https://core-electronics.com.au/3pc-heatsink-kit-for-raspberry-pi-4.html) not included
- This board is named "Fake HAT" due to it not being compliant with the Raspberry Pi HAT specifications (primarily due to its physical dimensions)
- It must not be used when another device is connected to the ID\_CD/ID\_SC pins
