Naze 32 voltage issue

[wallin]

Hello
I'm building my own drone right now and ordered the naze 32 rev 6 from hobbyking.
I've recieved it and started to test it out, when i tried to set up my reciever (Turnigy 9x) a problem started showing up. When plugging it in while the board still is only connected to the computer I couldn't get the readings to show up. After troublesshooting i noticed that the reciever didn't get power. When measuring the voltage between the +5V and ground that is wired to the reciever I only measured a voltage of ~0,5V.

I went too Hobbykings support chat, there they told me to try out with the battery attached, still didn't power it.
They thought the board was broken and sent a new one.

I recieved the new one and the same issue is still there, only 0,5V out to the reciever.

I would be very happy to get the answer if I'am doing something wrong and if there is a solution for it.

Best regards
Oliver

Theres a small circuit on your flight controller and or your pdb called a bec, it regulates a 5 or 12 volt output for vtx, receiver and etc. Your bec could be bad, but on both boards? are you sure you are using the proper rails/pads for your receiver?
Also, i highly recommend a more modern fc for your build, a f4 or f5. At this point, it'll only cost you $20- $45 and a little time waiting for it to be delivered, well worth it

Yeah, that's why im confused if im doing it wrong or if i really got two bad ones.
I've been measuring between these two points.
Thank you for your reply!

I'm pretty sure thats not what you need, what type of receiver are you using?

 

[VirtueViolater]

You have to feed that board with 5v from your pdb

 

[VirtueViolater]

1 sec.... i'm looking at manual

 

[VirtueViolater]

this will tell ya how to get 5v to it, just ask if ya have any questions, me or someone here will help ya out

Turnigy 9x8C V2
I've only tried it while powering it with the usb-cable so far.

I just watched through it, so I connect the 5V and ground from the PDB to those pads on the reciever-pin-row, as they power up the flight controller?
Or is the input voltage to the flightcontroller supposed to go anywhere else?

 

[VirtueViolater]

You are using the proper pads, the 3rd one is the signal from your receiver. You can solder a 5v and neg from the 5v output on your pdb or 4 in 1 esc to any neg and the center 5v rail on your naze 32

 

[wallin]

Okey!
Then I think I know how to proceed.
Thank you for taking your time to explain it to me!

 

[VirtueViolater]

The pic above, thats your 5v and ground to your receiver with the #1 pad beside them the other wire from your receiver. you also need the 5v and ground from your pdb to the fc using the center 5v rail and any unused groung pad on fc

 

[VirtueViolater]

The 5v rail is the one with the 90 deg pins installed
the center is the 5v

 

[wallin]

So I should solder 5V from the PDB to this positive row and then ground to any GND on the board?

 

[VirtueViolater]

yes, the ground next to it is fine

 

[wallin]

Great, I will try that! Thank you again!

 

[VirtueViolater]

Any time. I would check and make sure you are getting 5v out of the bec on your pdb before soldering

As usual Virtue, you are a great advisor.

I've now build the drone and tried what you told me. It works!
I have a Turnigy 9x reciever, it says on the controller that it's PPM. But in cleanflight it doesnt show my stickmovements. If i change it to PWM it shows.
Is it some other settings im missing out on or is this how it's supposed to be?

 

[VirtueViolater]

Try setting everything to sbus or ibus. 9x is the transmitter if im not mistaken, can you post a pic of your receiver?

 

[VirtueViolater]

That may be a pwm receiver, if it is, you will need 4 signal wires from the receiver to the flight controller instead of 1
