Hi,
I have a question concerning the power supply of an overo water together
with the Tobi expansion board.
I need to power both boards with an unregulated dc input voltage of
5-18V, therefore (afaik) I cannot get stable 5V to power the barrel
connector. After looking at the schematics it seems like one option
would be to directly attach 3.3V (SV1 Pin2), which is connected to
VSYSTEM and should power the COM module without problems. The only part
that needs 5V seems to be the USB interface. I could live without USB,
so might this solution help or am I missing something?
Any help would be greatly appreciated.
Thanks,
Oliver
