I connected cc3200 to power supply

during connection to AP cc3200 was restarted

so on the power supply output I added two capacitors 470uF 6.3V each

problem was solved !

thanks a lot for comments

P.S.

on pcb is little mistake I will fix it soon

ROC1 resistor have value 15.62 M (MPPT value 80% configuration)

in real world I had problem with buy,,, so I mounted two resistors 10M + 5.62M ( mounted in series both in 805 package )

Nice work.

The booster certainly makes small solar cells useful.

I have a few projects and was trying to deal with lower voltage storage then boosting it for the load, but this makes more sense.

Thanks for sharing it.

Lukasz Krysiewicz,

test results and anomalies? I was thinking of add the ROV and RUVs on the board using trimpots jumpers and fixed values. That will work?

Hi Lukasz,

Very useful info! I've been reading up on this device and the bq25505 recently.

The information above will be extremely useful for the 'In The Air' challenge too, so I think lots of people will benefit from this post!

Nice post on the TI charging chips.

I had looked at these earlier when TI brought out the battery booster pack and they looked very impressive.

It is good to see how easily you could use them in your own board. Good board work by the way.
