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.
