SPR F3 and Volo The Power

[Mudders]

Hey folks, I';m rebuilding my 250 for 4s, plus a few tweaks,

I want to power my SPR F3 board with a Volo the power PDB, if I power the SPRF3 board from the 6v supply on the PDB will it blow? There doesn';t seem to be a 5v option?

Thanks
Mat

I would be surprised if it survivevd being powered with 6v.
Its a pretty fussy board as it is, I wouldn';t want to feed it 6v

Just my luck. I suppose I need a 5V BEC then? So much for keeping it light!

As Yellow said, don';t go 6v on the SPRF3... No no no! Get a BEC or a pololu.

when I was building my quad I used a tiny reg with a screw and I turn it to 5.06 volts. after some bench tests suddently outputs 11.0 and that causes my d4r to burn. the flight controller survived by luck. its wasnt pluged. after that I bought a new receiver and a u bec that outpus 5-6 volts by switch. I will never use again these tiny regs. hope I helped.

The FC itself has regulators.  I believe they are 16V regs, but I can';t find it documented anywhere, so take that with an ounce of salt.

The problem is that VCC on all IO (except 3.3V) is unregulated.  So, if you fed the FC 12V that will be across all VCC pads.  The result is what happened to lamproGR above.  Since you probably power other devices from the FC you need to be aware of their demands.  5V is a safe bet, which is why it';s recommended.
