KK2.1.5 maximum input voltage

[gb0wers]

I';m currently flying a KK2.1.5 on a quad using a 3A ubec set to output 5.1 V, it also has the capability of outputting 6.1 V by a jumper change.

At present all I am powering with the ubec is the KK2.1.5 that will take 4.8 to 6V and a FrSKY XR6 that will take 4 to 7V, hence the 5.1V ubec setting.

I want to add a VTx and FPV camera. The camera will take 5 to 17V and the VTx 6 to 24V.

Based on the specs, the ubec 5.1V is too low for the VTx minimum requirement of 6V, but if I bump the ubec up to 6.1V its then too high, by 0.1V, for the KK2.1.5.

Please note that all of the voltages stated are specs, I have measured nothing, and don';t think I have the capability of measuring to 0.1V with any confidence.

Opinions are sought on the likely outcome of setting the ubec to output 6.1 V and feeding that to the KK2.1.5 please.

Thanks

What FPV VTx and camera will you be using? Most VTx´s connects to the flight pack voltage via PTB, not from the UBEC, and supports voltage to the camera together with the signal and ground. Check the diagram for your equipment

Thanks helinor.

That';s how I connected it in the end, I have just picked up a supply from the 3S flight battery, no filters or regulators but it works.

Not sure what a PTB is in this context, http://acronyms.thefreedictionary.com/PTB ;-))

Should have been a D not a T...
