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 LC709203F LiPoly \/ LiIon Fuel Gauge and Battery Monitor does the same thing.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eSince 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.\u003c\/p\u003e\n\u003cp\u003eTo use, connect a single-cell battery to one of the JST 2 PH ports (either one). Then use the included JST PH jumper cable to connect to your boost converter, Feather, whatever!

If you connect a 10K thermistor to the THERM pin you can also use it to read the battery pack temperature - our packs do not come with a built in thermistor but many do.\u003c\/p\u003e\n\u003cp\u003eTo get you going fast, Adafruit spun up a custom made PCB in the \u003ca href=\"\/en-eu\/collections\/stemma-qt\" target=\"_blank\"\u003eSTEMMA QT form factor\u003c\/a\u003e, making it easy to interface with.
