Shown above: The Agora ON/OFF switch 3.8V is the output of the main supply on the Agora board. It is regulated by an ADI LTC3539 which receives its input from the battery voltage terminals. For Agora configurations using the LiPo battery, the battery voltage is directly fed into the input of the LTC3539.
4.2V, the ADC reference must be set for at least 2.4V. With the battery voltage monitor characterized as a high impedance circuit, the ADC sample time must be set to the maximum setting.
