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/ADA5580:1.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) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description Low cost Lithium Polymer batteries have revolutionized electronics - they're thin, they're light, they can be regulated down to 3.3V and they're easy to charge. On your phone, there's a little image of a battery cell that tells you the percentage of charge - so you know when you absolutely need to plug it in and when you can stay untethered. The **Adafruit MAX17048 LiPoly / LiIon Fuel Gauge and Battery Monitor** does the same thing. Connect it to your [Lipoly or LiIon battery](https://core-electronics.com.au/power-batteries.html#category_307) and it will let you know the voltage of the cell, it does the annoying math of decoding the non-linear voltage to get you a valid percentage as well! Since this nice chip is I2C, it works with any and all microcontroller or microcomputer boards, from the Arduino UNO up to the Raspberry Pi. And you don't have to worry about logic level, as the gauge runs with 3.3V or 5.0V power and logic equally fine. To use, [connect a 1S 3.7-4.2V Lithium Ion or Polymer battery](https://core-electronics.com.au/power-batteries.html#category_307) to one of the JST 2 PH ports (either one). Then use the [included JST PH jumper cable](https://core-electronics.com.au/jst-ph-2-pin-jumper-cable-100mm-long.html) to connect to your boost converter, Feather, whatever! Use the I2C interface and Adafruit's [Arduino](https://github.com/adafruit/Adafruit_MAX1704X) or [CircuitPython/Python](https://github.com/adafruit/Adafruit_CircuitPython_MAX1704x) library code to read the voltage and percentage whenever you like. There are various alerts, low power modes that can be customized as desired. To get you going fast, Adafruit spun up a custom-made PCB in the[ **STEMMA QT** form factor](https://core-electronics.com.au/search?q=stemma%20qt%20sensor), making it easy to interface with. The [STEMMA QT connectors](https://learn.adafruit.com/introducing-adafruit-stemma-qt/what-is-stemma-qt) on either side are compatible with the [SparkFun Qwiic](https://core-electronics.com.au/catalogsearch/result/?q=qwiic) I2C connectors. This allows you to make solderless connections between your development board and the MAX17048 or to chain it with a wide range of other sensors and accessories using a [**compatible cable**](https://core-electronics.com.au/search?q=stemma%20qt%20cable). [QT Cable is not included, but Adafruit have a variety in the shop](https://core-electronics.com.au/search?q=stemma+qt+cable) ## Technical Details Product Dimensions: 25.7mm x 20.3mm x 7.2mm / 1.0" x 0.8" x 0.3" Product Weight: 2.6g / 0.1oz ### Shipping list - 1x Fuel gauge module ![RoHS 2 2011 65 EU Compliant](https://core-electronics.com.au/attachments/uploads/RoHS2_2011_EU.png)![RoHS 2 2015 863 EU Compliant](https://core-electronics.com.au/attachments/uploads/RoHS2_2015_EU.png) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/A/D/ADA5580-2.jpg)
