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:

• PiSugar2 $46 (I'll see how the 5k batt does and then maybe swap it for a larger capacity)
• 12-5v converter (2pk) $15
• INA219 (5pk) $16
• Data screen, might as well go big with this one, try to get it to cycle through different display outputs by touch $18

Power solution total = ~$100

You may want to look into the PiSugar 2 Pro. https://www.amazon.com/Pisugar2-Portable-Platform-Raspberry-Accessories/dp/B08D8PPCKN

It is supposed to be able to support the Pi 4 and also has a RTC built into it which can assist the pwnagotchi as well. I bought one but haven't taken the time to rebuild S1r Pwnsington yet.
