## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE09757:1` (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/CE09757:1.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

Super convenient for powering deployed projects using microcontrollers with wide range input like the [Raspberry Pi Pico](https://core-electronics.com.au/raspberry-pi/pico.html#category_2118), or [BBC micro:bit](https://core-electronics.com.au/micro-bit-australia.html#category_957).

With [Alkaline AA Batteries](https://core-electronics.com.au/aa-batteries.html) the voltage will be somewhere between 3.3 and 4.8 Volts and if you are [using NiMH batteries](https://core-electronics.com.au/panasonic-eneloop-pro-nimh-aa-batteries-2450mah-4-pack.html) somewhere between 3.0 and 4.2 volts. Both are similar to LiPo batteries but far less prone to dangerous failures.

Since both aren't LiPo's make sure you do not plug them into any LiPo chargers or raw 5V outputs!

Add one to your next robot or portable project - the on-off switch is recessed and harder to accidentally switch on and off, perfect for projects with lots of moving parts!

### Specifications

- Holds 3 AA Batteries in series
- Micro-USB Connector
- On-Off Switch
