The ESP32-H2 has a built-in brownout detector which can detect if the voltage is lower than
|
|
|
|
|
a specific value. If this happens, it will reset the chip in order to prevent unintended
|
|
|
|
|
behaviour.

The brownout detector will reset the chip when the supply voltage is approximately
|
|
|
|
|
below this level. Note that there may be some variation of brownout voltage level
|
|
|
|
|
between each chip.

|
|
#The voltage levels here are estimates, more work needs to be done to figure out the exact voltages
|
|
|
|
|
#of the brownout threshold levels.
