Looking for a 12-24v DC to 5vDC converter
I was wondering if anyone has ordered any step down regulators/converters from Ali that they trust? I am looking for one to power an Arduino/Mysensors build with 2 relays from a 16V DV 10VA source (door chime). I found one on Amazon.com, but they don't ship to Canada so I was thinking Ali and save some money anyways.
@AWI Hi AWI,
I've never used one of these before. I see the input voltage is 4-40V, but how do you adjust the output voltage?
If it's easy to adjust, i'll be getting a pack of 10 for sure. Thanks.
The blue thingy on there is a potentiometer. That one changes the output voltage. Easy to change if you have something to measure the voltage.
PS Just do it BEFORE you add sensitive other components
I use these:
Very small and sensitive potentiometer, but once adjusted they are stable. Smaller then the other model shown above, handles 1.8A continous and peaks up to 3A. Works at a higher frequency (1MHz) then the older design.
A second for these. I purchased from ebay about a year ago, more expensive but same unit. Working in 4 cameras.
