Features: Calibration Not Required: ModelGauge estimates remaining capacity without preliminary full battery cycling, with a stated ±5% accuracy specification for battery readings.
Low-Current Battery Tracking: Typical operating current of less than 1 μA limits the gauge's own contribution to battery drain while it measures remaining capacity and voltage.
Solderless I2C Integration: STEMMA QT and Qwiic connectors establish physical and I2C links without soldering, while address 0x36 provides a defined interface point.
Defined Single-Cell Use: Built for 2.5-4.5 V single-cell lithium batteries with CircuitPython driver support; do not use it with multi-cell series packs or other battery types.
Package Contents: Includes 1 battery gauge module and 1 pin header; verify battery polarity and avoid connecting or disconnecting the interface while powered.
