Powering Gadgeteer

Can I supply 5V on a Gadgeteer port to power the entire system?

This is exactly what an USB SP or USB DP module does.
But If I’m right, it also supplies the 3V3.
So yes and no.
Yes you can supply it with 5V by any port.
and no, you also need to supply the 3V3.
Except the board would have an regulator for 3V3 onboard, but if I’m right a pure Gadgeteer board does usually not have an regulator.

Ohh… that’s true.

On my CerbBee there is a Vin pin. (Its been so long that I can’t recall). Can I supply 5V there?

Ok I recall now. thanks.
