Connect it to your \u003ca href=\"\/en-eu\/search?q=bat0\" target=\"_blank\"\u003eLipoly or LiIon battery\u003c\/a\u003e 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!\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 1S 3.7-4.2V Lithium Ion or Polymer battery to one of the JST 2 PH ports (either one). Then use a \u003ca href=\"https:\/\/shop.pimoroni.com\/products\/jst-ph-2-pin-jumper-cable-100mm-long?variant=40082550128723\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eJST PH jumper cable\u003c\/a\u003e to connect to your boost converter, Feather, whatever! Use the I2C interface and the \u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit_MAX1704X\" target=\"_blank\"\u003eArduino\u003c\/a\u003e or \u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit_CircuitPython_MAX1704x\" target=\"_blank\"\u003eCircuitPython\/Python\u003c\/a\u003e library code to read the voltage and percentage whenever you like. There are various alerts, low power modes that can be customized as desired.\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\u003c\/a\u003e form factor, making it easy to interface with. The STEMMA QT connectors on either side are compatible with the \u003ca href=\"\/en-eu\/collections\/qwiic\" target=\"_blank\"\u003eSparkFun Qwiic\u003c\/a\u003e 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.
