Hi,

Just received the SunControl board, and had a chance to pull apart my previous weatherstation to get it installed. I don't have a LiPo connected yet (still waiting on shipping), but wanted to at least power it up and connect to I2C to see what I can see.

Problem is that if I power the RPi via the USB A port on the SunControl and power the SunControl via the USB mini port and an AC wall adapter, the RPi will never fully boot - it resets right before the console comes up. It seems to be about ~40 seconds. Should I not be powering the board with just the USB mini connector and nothing else?

For a Pi3+ you'll need a 2.5A supply. For older PIs quite a bit less.

And the battery needs to be above the 3.4-3.5V level. BP

I now notice that the charge\done LED never turns on on the board this originally started with. The other SC board works great.
