If the Raspberry Pi B+ is not receiving enough power and I try to use it, will it damage my Pi or peripherals?

I doubt it.

If it is writing to the SD card then the card filesystem may be damaged.

The most likely action is a Pi reboot.

We don't know what peripherals you may attach. You would have to look at them on a case by case basis. I reckon there would be great big warning labels on such a peripheral if it was susceptible to such damage.

  • Some peripherals that have multiple voltages and voltage regulators may encouter issues if power sequencing cannot be followed, such as if one regulator cannot output a sufficient voltage, and it causes logic to, for example, drive pins improperly. IOBs of FPGAs come to mind, but I don't have a reference or anything beyond a hunch for this. – ζ-- Oct 16 '15 at 23:26

(Edit) (It may be possible but probably not likely. What happened to me was that I had a bad HDMI cable)

I think it may be possible to damage the board its self. but it would have to be investigated further.

I connected my Pi to a 5v USB battery pack, Immediately the Pi began to show errors like no sound and video distortion on static pictures, Flickering and monitor turning off and on.

I then swapped the power supply to the one I've been using without problems and it did it again exactly like it did with the battery pack.

I then swapped the SD card to a known good one with the OS already installed and it did it again.

The only way for that to happen to my knowledge is because the Pi itself is messed up and is corrupting the cards.

I then put one of the messed up cards into another pi and it did the same thing. I'm hoping that it didn't permanently mess up the other pie or the SD cards.

I'm going to go get another pi and I want to investigate further with the same SD cards but I'm afraid to mess up another pi. So I think I'm just going to start over.

  • So, after swapping out the software and seeing the same results, what does that leave? Hardware. Power supply, to be specific. – SDsolar Apr 15 '18 at 4:36

    You are right it was hardware. I had a bad HDMI cable. Why did the problems start right after the low power I don't know but all of it is gone now that I changed the cable. – Maskedsquirrel Apr 17 '18 at 13:35
