ESP32 - Brownout

[Cpt.America]

Hello there.
I've been developing to the ESP-32CAM board for a while as well as other espressif boards.
I've been wondering about brownouts - why do they happen, and could it cause damage to the board?
Thanks in advance

They happen because something in your power supply chain can't deliver enough current, causing the voltage to the ESP32 to drop below a certain set level - this triggers the brownout detector. It shouldn't be able to damage the hardware (aside from maybe overloading an under-specced LDO or something, but that is not caused by the brownout, rather the other way around) but depending on how your software is written, it may not like suddenly being reset.
