## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=COM-15208:1` (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/COM-15208:1.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 SparkFun Buck-Boost Converter is a handy power accessory board that allows you to fine tune the amount of power your project receives. This converter can take an input voltage of anywhere from 3-16V which can then be regulated to an output voltage between 2.5-9V. With the switch on the bottom of the board, you can set the common output voltages of 3.3V and 5V, but we've also added a custom setting that allows you to solder a resistor based on your custom voltage needs. The GPIO pins have also been broken out along the top of the board for even more control!

In addition to the voltage control, the SparkFun Buck-Boost Converter uses a switching DC/DC converter, which is more efficient than a linear regulator. More efficiency means less energy is wasted in the form of heat. With built-in overtemperature protection and an optional heatsink, you can achieve up to 95% efficiency rating.
