Hi all,
im looking slowly since few weeks about how to build a FPV. Not for hardcore piloter, just for the fun, for some sensation
And after maybe... let say, it's my first shot haha

So here my list of material
   

I'm still thinking if my TX will be taranis or cheaper but good for beginner : AT9 from radiolink... but I think it is not the first think we broke when we start so let see it like an investment haha
On the package I've found there is the TX and RX together (welcome TAOBAO!!!!)
The ESC 4in1 was not my first choice but I believe it will make my life easier...
impeller i put these one but honestly... i dont know...
flight controller is I hope ok... with osd betaflight, no PDB
the frame ok is big, but why not...


and here the wiring:
   
The wiring I have a big question mark. 4in1 esc I think its ok, not to hard, there is a special connection between this one and the flight controller. Im just not sure about the other part of this 4in1... there is a output cur_sen, bat_sen, etc... according to the documentation :
cur_sen: is current sensor connect to CURNT pin on omnibus f3/f4 to detect current
BAT_SEN is vbat output connect to VBAT pin on omnibus f3/f4

The cabling of the lipo is it ok? I mean i will bring to the 4in1 and then make a bridge to the flight controller which can receive the lipo.
then the camera and vx I hope is ok...
The RX same, I think no mistake? I've the connection in SBUS mode... but not sure if I have to do something with the omnibus as on it there is (screenshot from 3 differents doc):
   


but what is all the output/input SDL, SDA CRNT, RSSI etc...?

thank you by the way for your support!

What I am about to tell you is unconfirmed research only... if I blow up my quad tonight it'll be because I was wrong. I can confirm tomorrow that it's ok if the quad doesn't blow up.

It just so happens you're using almost the exact same components as I am (your ESCs are similar but slightly different, and the camera also)

First, I believe you should be good to go direct to the lipo based on your power wiring. I spent an hour researching this and found that pretty much every source I could find slightly-confirmed it to be true... but there was always extra info that made me question. I think we're good on that one.

Next the ESC hook up... pay extra careful attention to which wire is for which motor. 3 and 4 were swapped on mine... This might have been on purpose since my ESCs had 3 and 4 backwards but I still corrected it and cross-wired the motors. The build might be cleaner if you leave them swapped but I cant vouch for the ease of build either way :p

As for battery voltage, if you're hooked up to pins that you show in the diagram from my understanding it's supposed to be able to read your voltage and power the board at the same time.

On the Rx: your wiring looks correct, I believe you only have to do anything with the jumpers if you want to use PPM. As your receiver appears to be an X4RSB if you hook up to SB you should be good.

If I have anything wrong here, please someone correct me. I can only go off of what I've read, but I am happy that you posted this thread Lurne because seeing your assumptions helps me assume that I might be OK on my end

Haha great!
Yes and I made some update following watching the video from here:
channel Project Blue Falcon, video: Adding Camera & Vtx to omnibus OSD
He has a playlist for the omnibus very useful! I can't put any link as im not on my personnal laptop = no vpn = youtube blocked. China....
Just for the RX and PPM/SBUS... didnt get exactly your meaning.... Like that?
   
Hope no because really small :'(

So yes I made the jumper for 5voltage on the FC in order to powered the VX and camera. I have two point:
- I've heard its better to have a common GND for VX and camera... whats that mean? Should wired on the same GND???
- following the video from youtube, its make me little bit worry about the powered supply... I don't understand exactly what is the benefits of a filter for the 5voltages, does it more clear on the display? He is recommanding a PDB... but already 4in1/FC + a PDB? will take place :'(
So i'm looking for another 5voltages supply which could be filter and OH! my 4in1 esc have some free 5V/GND
   
Do you think I could use it? In this video he said can take another 5voltages from somewhere else from the FC... So i assume I can...

So just again, here the cabling
   
+ my jumper like that in order to supply the 5v to the camera...
   

I updated also the drawing for the RX as following:
   
Just using the TX1 connected to the S.PORT.

and finally only the 4in1 ESC connected to the FC:
   

just a note, I will upgrade the motor for emax RS2205 KV2300.
by the way carl.vegas, which one are you using?

So for starters, an update on my go with this stuff... last night I went to power up and while nothing blew up, I also didn't get power yet. I think it's my smoke stopper though. (Correction: it was the smoke stopper. Quad powered up just fine but I am having some issues with my receiver so more to come) Anyway, as I said before... take what I say with a grain of salt as I am a first timer too and could be wrong about anything I say. I mostly share in order to confirm from a "yeah that looks like how I learned to do it from random websites too"

I think I found it here:

I'll have to watch it. It was one of his videos that I used to confirm that the FC could be powered directly. I've already wired up my camera but if I have issues I may give it a shot.

I believe you do not have to do any jumpering on these if you're using SBUS for the receiver

On the common ground, my guess is that it has to do with reducing the amount of noise that could be introduced by having other electronics between the two devices but I am not positive. This is a topic that I understand RF just enough to have some basic theories. Having filters for the power is also to reduce noise which can interfere with the video system and degrade the video. From examples I've seen it looks like interference in the analog video transmission.

I realized after the fact that I have a different VTx than you do. Mine takes 5-22v and outputs 5 so I am using the transmitter to supply power to my camera. I am hoping that this achieves a good result but if it doesn't then I may try your way. Unfortunately I'll need new cables because I butchered mine when splicing them and I fear it would be impossible to re-solder my negative power out wire.

All 3 are techniques I have not looked up myself so I can't say if it's right or not. I also realized that you're using the F3 FC and I am using the F4 version. The biggest difference is that yours has the SD card slot and mine doesn't... hopefully I wont need much for blackbox logging

best of luck, and I do wish someone with more experience might come in and agree or disagree with some of the stuff that either of us are suggesting I feel a little bit like the blind leading the blind but even if not I definitely appreciate the opportunity to share notes on such similar builds! (here is my build thread BTW)

On this build I am using the trusty old Cobras... it's funny because I think they were like the standard for great performance just about 6-8 months ago but now those emax race specs seem to be pretty popular. I also have read good things about the Diatone d-silvers

yes same for mine. input 5-22 and output 5v. But thats strange because where i have to wired it is the output so 5v.... On a french forum they advised me to be in 12v.... put then I have a doubt....

I wanted to come back to this as I've since powered up mine, everything is looking good and I've really confirmed a ton of things... I see some re-wiring that really worries me here. 

I want to cover the part that I said I didn't know about.

your jumper to supply power looks right based on the video you posted before. If you require 5v then it should work

(10-May-2017, 01:22 AM)Leurne Wrote: Your previous wiring would work fine I think unless you're trying to do some advanced telemetry stuff that I haven't read up on. 3 wires are all that I've ever seen having been needed for SBUS: +,-,S

I have used the exact same config you show in this screenshot minus the green wire.

and finally only the 4in1 ESC connected to the FC:

lastly... when I re-visited this one I realized are you talking about powering the ESCs from the FC? I am no expert on this... but that sounds like waaaaaay too much for a flight controller to handle! My guess is that circuit would cause resistance, heat up and cause problems... power the ESCs from the PDB. That's what PDBs are for
