A buddy of mine bought some USB buck converter boards and was going to make an adapter cable and I had the idea of this box instead.
It has one set of power poles in and 2 sets out, and then USB to power a PI, what have you.
This box is great for POTA FT8. battery in, PI, Radio, Tuner power out.
It has gone through a couple revisions hence the different color boxes.
You can either crimp multiple wires into the single set powerpole to the double or crimp one wire in each connector and then solder them all together, we have done it both ways and they both work.
Yes, I know some of the pictures have the power pole polarity reversed, that has been remedied.
Here is the link to the buck converter I used.
