What is the source of power for the Naze32 flight controller?
Hello again.
My question this time has to do with the power distribution or flow within a quadcopter. It appears the motors receive power via the ESCs and the ESCs receive power from the on-board Li-po battery.
It also appears that the power from the receiver is supplied via the Naze32 flight controller. Where does the Naze32 get its power?
Do I need to provide 5 volts to the Naze32 via a regulator connected to the on-board battery?
It appears some ESCs provide 5 volts on the signal side of the device.
Any guidance or suggestions are appreciated. David
Hi, Thanks for your question,
Some ESCs have BEC (battery elimination circuit) built in, whereas other escs (opto) do not.
If you have an ESC with a built in BEC then this means that it gets it’s power from the lipo battery and then steps down that power to 5v and sends that through the servo lead. So when you connect the servo lead to your Naze32 you should get 5V there, and that 5v in turn powers your Receiver.
Many Escs however don’t have a BEC built in. This is especially true for high performance ESCs such as Kiss and BLHELI SN20s
So when using these escs, you have to power the Naze32 with an additional source of 5V power. You can do so with a standalone BEC, or (my favorite method) use an OSDoge to provide the flight controller with the 5V that it needs.
