The LC709203F includes an advanced charge monitoring system that provides precise information about the battery charge as a percentage and the battery voltage. The sensor communicates directly over the I2C bus either via pin header or STEMMA QT connector, making it easy to integrate into microcontroller-based projects. A wide operating voltage range (2.7–4.2 V) makes it compatible with most LiPo and LiIon batteries. This module is specifically designed for battery-powered applications such as portable devices, IoT projects, and monitoring battery-powered equipment.
