## Description

Keep an eye on your single-cell LiPo battery before your project suddenly runs out of power. This compact fuel gauge board sits in circuit with your battery and reports the relative state of charge using the MAX17043 fuel gauge IC.It combines a charge-estimation algorithm with direct A/D measurement of battery voltage, giving your microcontroller a practical way to know how much “fuel” is left. Communication is over I2C, and an alert pin can notify your project when the charge drops below a set percentage.Supporting resources include schematic and Eagle design files, a hookup guide, the MAX17043G+U datasheet, a Fritzing part, C example code, and libraries for Arduino, Python / MicroPython / CircuitPython, and Particle Photon.Features:Fuel gauge system for single-cell lithium-ion batteriesCan be connected in circuit to monitor the battery.Hardware and Software Reset.I2C Interface

**Product Type:** Battery Monitor
