I want to make mini computer and I want add button for on/off power button. I will change config.txt with dtoverlay=gpio-shutdown. And then add button between GND and GPIO5. There has written that it will start: https://www.raspberrypi.org/forums/viewtopic.php?t=217442

I read and watched many posts and videos, but I've question - Is there risk for burn RPI 3 B+? And is there any way without any risk?

  • What makes you think there's a risk of burning the pi? Did you read it somewhere? What's the context?

  • I'm afraid that it can burn. Because there is power and it can end with smoke.

No, if you connect a button between GPIO3 and GND and use GPIO3 as an input, there is no danger of you burning the Pi. No significant power goes through the switch - it is a signal only.

Adafruit made Read-Only Raspberry Pi which means you could use the wall socket switch without risk of corruption etc.
