Just had a quick question that I'm sure is very easy to solve but I just want to make sure before I purchase anything.

I'm working on a project, and I have a 12v battery. I want to power a raspberry pi in this project, but don't want to buy a separate 5V battery.

Here's the battery on amazon: https://www.amazon.com/26-SEALED-VOLT-DEEP-RECHARGEABLE/dp/B007GCDDOA/ref=sr_1_1?s=industrial&ie=UTF8&qid=1502323193&sr=1-1&keywords=12v+25ah+battery

I'm assuming I would need a resistor, but I'm not sure which one.

Also, would the 12V battery be too much for a breadboard to handle? Would it melt? I can solder if I need to but would like to use a breadboard for testing.

Any help would be appreciated!

That battery is probably overkill, but could be used.

DO NOT even try using a resistor. This will destroy the Pi.

You need a 5V regulator; I suggest a Switch Mode power module. There are readily available inexpensive modules which take a higher voltage, and produce a well regulated 5V.

See Raspberry Pi Power Limitations for more info.

  • Do you think this would work: adafruit.com/product/… – flakeyjake Aug 30 '17 at 0:36
  • @flakeyjake yes that would work – Charemer Aug 30 '17 at 12:02
  • @flakeyjake I use that specific UBEC from Adafruit and have no problems at all. – Brick Aug 30 '17 at 12:10
