B+ Power Supply Question

Sun Mar 29, 2015 11:22 pm

I'm working on a project to turn one of my Honey Bee Hives into a smart Hive with the B+. Question I have is will the B+ run fine on a 12V @ 1.2 AMPs?

I'll be running the PI, 12V Fan, 4-5 Sensors, camera and WiFi.

I can drop the power supply down to 6V @ 1.2 AMPS if anyone thinks that will be enough power.

The B+ (or any other Pi for the matter) works on 5V. Feed it anything bigger and it will wave you goodbye.

So 6V is out of question also?

Step down from 12V to 5V is easy and cheap. Get a car USB charger and use that. http://www.ebay.com/itm/Dual-USB-2-Port ... 19eaeddfd0

You can attach wires to it directly or buy a DIY wire-in 12V socket at an auto-parts store etc.

Do not try to use the Poundland item which has 2 cigarette lighter sockets and a USB 5 volt output. Its electronics consists of nothing more than a solitary 78L05 type regulator in a TO-92 package. Plastic package, no heatsink of any kind, dropping 9 volts. It won't power or charge anything requiring more than a miserly current before overheating and shutting down.
