- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/CE08578:1.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.)

- **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 I2C Breakout shield is an essential tool for any electronics enthusiast. With its dual sets of STEMMA/QWIIC/PiicoDev connectors and pin headers, it allows for seamless connectivity to a wide range of I2C devices.

This innovative shield features two 3v3 power rails. The first is always on, ensuring continuous power supply to your devices.

This automatic shutdown ensures energy efficiency, conserves power and enhances the longevity of your devices.

The shield's design also includes convenient solder jumpers on the back of the board, which enable you to select which IO to use for the 3V3 power control. This customization feature adds to the shield's versatility and ease of use.

The I2C Breakout shield is the perfect solution for anyone seeking to streamline their electronics projects. Whether you are a hobbyist or a professional, this shield will provide you with the power, control, and flexibility you need to bring your ideas to life.
