6 x Mini MP1584EN DC to DC buck converter
You can adjust the voltage by placing a multi-meter on the output, synchronously, using a screw driver to adjust a potentiometer. It can be minute adjustments to achieve a precise voltage.
These boards are adjustable current limiting, fixed 3A current limit.
Please make sure that this module within its working range before using.
Please don't output short circuit, otherwise the board would burn out.
When setting the parameter, please make sure output voltage is stable before using the module to avoid any possible damage.
Please check if the product package is intact before opening.
Please check if the negative and positive terminals are accessed correctly before operating.
The input voltage should not be over 28 V to avoid damage.

If you cook the coil on it it does NOT allow full voltage to pass through (I have had some buck regs fail and allow full voltage to pass through for a few seconds.. I killed two of these intentionally to make sure that when it failed no voltage pass through and on neither one did that happen and that makes me VERY HAPPY. A failure acts like a breaker, it fails it fails and circuit is instantly broken.. I tested this with a O-scope and it had 0ms of full voltage seep when it failed..) These are incredibly cheap and excellent quality.. over preform and stay dang steady.. These are without a doubt the best cost to preformance ratio bucks you can buy...
Bucks are not a place to skimp and buy as cheap as possible BECAUSE a failure on a buck that is supplying constant regulated voltage to high dollar electronics and fail and allow unregulated voltage to seep by for even a 1ms can damage sensitive to voltage electronics and ruin your day and make you wish you wouldn't have saved that 30 cents per piece.

I had a feeling something under $2 each wouldn't work out. I'll keep these because they can still come in handy.
HOWEVER - this only applies if the INPUT VOLTAGE AND DEVICE VOLTAGE ARE WITHIN 3V OF EACH OTHER. In other words, if your stepping down more than 3v you are safe to keep your devices turned off with this converter inline.
Example: I am stepping down a 12v signal in my car. The variable output on this converter is set to 5v. 12 - 5 = 7v. 7v is > 3v = SAFE.
I was a little hesitant to buy because some of the reviews stated the difficulty in adjusting the power setting screw.
For me I had no problem getting it exactly as needed.
1 is used to power an Arduino and the other for a PI-3.
