Providing power to pi 0 W outdoors

Sun Nov 10, 2019 11:04 pm

I am new to the raspberry pi world, and am working on an outdoor security camera system using pi 0 Ws running motioneyeos. To provide power I was thinking of using a landscape light transformer with a 12 volt to 5 volt DC-DC converter connected to the landscape wiring to power each pi 0 W ( something like this - 12V to 5V 3A Step-Down Waterproof Miniature DC-DC Converter Power Supply Module - found on amazon). So I thought I would ask folks here if they thought this would work or not?

Thanks for responses (also any options\criticism).

That should work fine.
I have a similar solution running on a 12V lead acid battery.

Make sure the lighting supply is DC not AC. If AC you will need a rectifier and smoothing capacitor. This will produce DC close to the peak AC voltage, check that it is still within the converter's input voltage spec.

Got one running like that, other Pi B's using cheap POE setup.
