M5 with ADC does a reset
-
Hello everybody
I measure the voltage of a 3.2V LiFePo4 cell of a solar battery on a Fire with the ADC unit via a voltage divider (2x15kOhm).
When the sun comes out, the M5 sometimes resets...
What can be the reason?

what's the voltage when the sun comes out?
you would be better of using a VMeter unit instead of the adc to measure voltage as under high sun it could be overloading the 3,3v max input pin causing the reset.https://shop.m5stack.com/collections/m5-sensor/products/voltmeter-unit-ads1115
