Yes I have thought of that, but I was looking for something non-user dependent (during testing you don't change versions all the time).

What about running a checksum on the flash, and comparing that value to the last value saved.

I hope ESP team will consider this issue seriously.

Just curious, why would ESP team try to fix something that Adafruit wrote?

Try using the setup for the examples folder. It's a bit different than what you have.

Did you follow the footprint recommended form the data sheet ?

My question is if dealing with the reversed polarity could damage the GPIO pin or even the whole board. Basically Yes, If you look at the schematic for the board 5v goes through a 2k resistor to one end the led and the other goes to the the charge controller (pin 1). To be safe you could either A) ...

Just use a transistor or fet to power your PIR, and control it though a GPIO pin.

Maybe something like this? Trigger it with one of your GPIO. https://www.amazon.com/HiLetgo-Trigger-Adjustable-Control-Conduction/dp/B0832MW9L4/ref=sr_1_6?crid=2AQX3POCR5PLS&keywords=digitally+controlled+power+relay+with+time+delay&qid=1707712926&sprefix=digitally+controlled+power+relay+with+time+de...

remove the ESP_LOGI's from the ISR handler and see what happens.

need to supply a little more to the story.
What voltage are you supplying the L7805CV ?
Did you put filter caps on the input and output, and if so what are they.
