Ooof lots of options, some pricier than others.
What are your thoughts about using a Pisugar2 with the 12v-5v step down converter connected to the PiSugar2's power input? Basically, do you think this will work or will it blow it up?
As for sensor reading: The more I read I think 3.2A is sufficient, so I can use a string of INA219 sensors to have the Pi monitor different points of my system for output to screen.
I'll probably wait on the connectors for now, I like powerwerx but I should probably see how it all fits together and what case I end up with before getting those.
So in total:
Power solution total = ~$100
I am working on a project which uses this display and needed an enclosure. Using some enginerring drawings I found for a similar display I had an enclosure designed and 3d printed within just a couple hours. Fun stuff!
