Hey,
my plan: working with an T3.5, which is powered on VIN with 5V. When power is lost, I want to save data to eeprom. Idea: feed the 5V into a GPIO and measure. Put an extra Cap on the 3.3V line, which holds the 3.3V line long enough to save data when a LOW is detected on the GPIO.
Is this feasible?
Will this lead to a problem with the voltage onboard voltage regulator?
Thanks
