# ModMyPi Triple GPIO Expansion Board w/ HAT Area

**Type:** Product page · **SKU:** CE05843 · **Brand:** [The Pi Hut](https://core-electronics.com.au/brands/the-pi-hut)
**Page:** https://core-electronics.com.au/triple-gpio-expansion-board-w-hat-area.html ([markdown](https://core-electronics.com.au/triple-gpio-expansion-board-w-hat-area.html.md))

This triple GPIO multiplexing expansion plate is perfect for sharing GPIO pins between applications and circuits! It's often fiddly to combine multiple breakout boards onto the standard single Pi GPIO header, but with the expansion plate, it's a breeze.

## Pricing

- **Price:** $17.85 (inc GST) — $16.23 AUD, exc GST
- **Quantity discounts:** 10+ $15.58 (exc GST) · 25+ $15.09 (exc GST)

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE05843:1` (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/CE05843:1.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

This triple GPIO multiplexing expansion plate is perfect for sharing GPIO pins between applications and circuits! It's often fiddly to combine multiple breakout boards onto the standard single Pi GPIO header, but with the expansion plate, it's a breeze. Simply plug the replicator board into your Pi and plug any additional circuits or breakout boards into additional headers! This board is fully assembled and comes with 3 x 40 Pin headers, so you'll have up to 4 x 40 Pin GPIO arrays to add "stuff" to your Raspberry Pi.

This board has a HAT mounting area, so you can mount two HATs on a single Raspberry Pi, and still have GPIO's to spare!

The product comes fully assembled with ModMyPi's push-fit "plug & play" Single Shroud Header, Socket Header, and 14mm HAT Mounting Kit, so there's no soldering required.
