Dave, does the DROK allow you to have it power-on with the USB port active? ?I bought some of these in the past where you have to go into a menu after turning on the power and then select the USB power output to be enabled. ?After turning off the main supply and turning it back on, the DROK reset (of course) but comes up with the USB output disabled. ?I had to go back into a menu to turn it back on. ?Is this still true??
?Thanks!

Update on my project. I have tried both of the following buck converters with good results. I’m only running a fan, USB-Serial, and a soundcard so I’m not loading it much.
The DROC meter should not be believed but its not far off. Both have operated on my bench from the same DC supply that is running my IC-7300 and I haven't noticed any noise.
I have also used them on a Pi 3 and the most significant factor is getting away from off-the-shelf micro USB cords and using cords intended for power.

So far no low voltage warnings on the Pi 3.
I have also added a Pi Power from Sunfounder and it seems to be working well. It has some suggested safe shutdown software so I am going to add that to the Pi.

Thanks for the suggestions.
