Adding battery and charging circuit
#7
I like the Geekworm Raspberry Pi 3 Model B/2B Programmable Smart Temperature Control Fan+Power Hat Board.

Takes input 6V~14V so there are quite a lot of LiPO/Solar circuits you could mate to that.

https://www.modmypi.com/raspberry-pi/bre...s/ups-pico if UPS / Lipo charger / Fan circuit but I hate those crappy mini-usb connectors, bit bloat and a bit expensive.

Have a look on the geekworm store on aliexpress as they have a ton of goodies.

You are prob going to have to do the tinkering and check all is compatible and apart from the modmypi one they should be as the power pins will be the same.
If those 2 geekworm boards mated and gave birth to something like the modmipi board, without the bloat it would be great.
Also what would be greater is if a graphics card Radial Cooling Fan was adopted https://www.aliexpress.com/item/2PCS-Gds...94778.html
As it solves the stacking problem of hats / boards

Guess you could build your own software i2c pwm radial fan cooler really cheaply if you can do the tinkering.

You could go fan nuts and have 16 of them Smile
If you inverted (nor) the mosfet pwm signal it would run full speed until the software loaded.

Your Lipo could sit on the top for your active cooled UPS Rock64.
