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

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