MPU9250 maker Balanced Charge Algorithm: CC-CV charging

MPU9250 maker Balanced Charge Algorithm: CC CV charging Balanced Charge Algorithm: CC CV charging protocol automatically adjusts current to optimize battery lifespan and maintain cell voltage balance across multi cell packs Wearable Fitness Tracker: Integrate into an armband to monitor muscle engagement intensity during workouts and display stats on a companion app while the accelerometer estimates displacement through double integration (though acceleration bias limits accuracy) High Speed Data Acquisition: 4kHz sampling rate with 512 byte FIFO buffer accommodates burst data collection for advanced motion analysis and gesture recognition
