Re: GPIO pin control, simple applet exists?

Here's the 12v to 5v converter I'm going to try, not easy to find cheap converters that are rated to handle a raspberry pi or two plus some other microcontrollers using wifi, the amps add up quick:?
Just going to diy a hub with some female usb a connectors I have lying around, 3d print a case.
I don't know if smart phones & other devices can still safely use "naked" 5v sources like this, or need "smart" charging ports. I don't plan on using it for phone charging, just?rpis.
Great topic. I don't really have a battery back-up system in the shack. But with all the power outages in my area lately, been thinking about a PWRgate with AGM battery. More than operating for EmComm, I really need something for basic power for my work laptop & phone w/ wifi hotspot. Thus, it would be good to build a down converter hub for 12V to 5v USB power to operate all my 5V devices. The laptop battery generally lasts all day.
