Product description
Battery fuel gauge module based on the Texas Instruments BQ27441 for accurate monitoring of lithium battery charge status. The module is designed for 3.6/3.7 V Li-Ion/Li-Po batteries and measures battery voltage, state of charge, and remaining capacity. It is suitable for battery-powered projects, IoT devices, portable electronics, and other applications where battery status monitoring is required.
Communication is via I2C, and the module is equipped with two Qwiic connectors for quick solderless connection. The board features a JST connector as well as an alternative quick-connect terminal block for Li-Ion/Li-Po battery connection.
