SPIDER Automation Adafruit MAX17048 LiPoly/LiIon Fuel Gauge | 1S Battery Monitor & I2C Interface | For Portable & Battery-Powered Electronics
Description
The Adafruit MAX17048 LiPoly/LiIon Fuel Gauge and Battery Monitor is a compact battery-monitoring solution for 1S lithium-polymer and lithium-ion batteries. It is designed to provide useful battery-status information without requiring a dedicated analog battery-measurement circuit, making it suitable for compact embedded and portable electronics.
The onboard MAX17048 fuel-gauge IC measures battery voltage and provides an estimated remaining charge percentage through an I2C interface. This allows a connected microcontroller or development platform to read battery information digitally and use that data for monitoring, status indication or power-management logic.
The board supports batteries in the specified 3.7–4.2V 1S range and is designed for systems using either 3.3V or 5V logic levels. Configurable low-power modes and alerts provide additional functionality for battery-powered applications where efficient monitoring and battery-status awareness are important.
For simplified hardware integration, the board provides STEMMA QT connectors for solderless I2C connectivity with compatible development boards and sensors. Two JST PH connectors provide convenient connection options for battery-related wiring, making the board suitable for rapid prototyping as well as compact embedded system development.
