A super cap UPS for rpi boards that does what it claims
For Smart UPS Supply for Raspberry Pi & Power Button
What can I say... it does everything that is advertised!
It is pretty much a plug and play solution, it took me 30 min to go over the documentation, plug it and test it.
I am mounting this in an arcade cabinet, so I cut a usbc cable and wired it straight to a 5v 15a power supply.
The maker is very friendly and responsive over email/comments, he answered my questions overnight (this is as fast as I can expect it, given that my timezone is 12 hours away from Germany).
I read some feedback by other users about the documentation, mostly asking for a pdf that summarizes it all. Although it is true that a pdf could help, if you take the time to read all the html documentation you will realize that it is very well documented. You get the technical specs, schematics, configuration for the rpi when needed, the firmware for the microcontroller, and even the ability to message the maker!
