A9G Module Battery Monitor: MAX17043 Fuel Gauge with MicroPython (I2C Tutorial) | Bangla
Learn how to interface the MAX17043 LiPo Fuel Gauge module with the A9G GPRS/GPS module using MicroPython. In this tutorial, we will measure the accurate battery voltage and remaining charge percentage using I2C communication.
Unlike standard ADC readings, which can be inaccurate for LiPo batteries, the MAX17043 provides precise data via the I2C interface. This is essential for battery-powered IoT projects to monitor power levels remotely.
