## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA1868:1` (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/ADA1868:1.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

**Warning: This product requires a button battery to operate which is hazardous to young children. Do not use this product for projects that are potentially accessible to young children.**

Simple but effective - this breakout board has a CR1220 coin cell battery holder soldered on and 0.1" pitch breakout pins for easy connecting. Great for powering very low-current projects, or adding a battery backup circuit to a real-time-clock or similar.

Comes with one fully assembled and tested coin cell battery holder and a small stick of 0.1" header so you can solder it on and plug into a breadboard.

[We also have a version with an on/off switch](https://core-electronics.com.au/12mm-coin-cell-breakout-w-on-off-switch.html)
