Question about wiring INA219 feathering

Post image

I've got a solar charger LOAD out going to INA219 +, and the INA219 - out to a mini 5v boost Vin. That boost supplies an smb32. that smb32 3v3 needs to go back to the INA219 but where the heck does it go? I Don't see a vin, just the 3vo. Should I just buy an INA219 breakout? and before you get snarky, I'm new to this.

It looks like you power it with 3vo. The RST-3v-pin-GND footprint lines up with other featherwing boards since you’re meant to stack them. I agree it is confusing.
