Gravity: 3.7V Li-ion Fuel Gauge
Overview
The DFR0563 is a specialized battery fuel gauge expansion board designed for 3.7V single-cell lithium-ion and lithium-polymer batteries. It utilizes the MAX17043 chip with a high-precision algorithm to monitor relative state of charge (SOC) and voltage via an I2C interface. The board features Gravity series connectors for simple integration with microcontrollers without complex wiring.
Why Choose This Part
The module consumes an ultra-low operating current of only 0.05 mA, making it ideal for battery-sensitive applications. It operates across a supply voltage range of 3.3V to 6V and eliminates the need for complex shunt resistors or current sensing by using the ModelGauge algorithm.
Applications
Key Specifications
Getting Started
Connect the battery to the JST-PH terminal and the Gravity 3-pin connector to an I2C-enabled microcontroller like an Arduino or ESP32. Use the DFRobot_MAX17043 library to read the state of charge and set a low-voltage interrupt threshold. The board's dimensions are 22mm by 30mm, fitting easily into compact enclosures.
