- Howdy, in this episode we'll be soldering on the connectors to the GPS unit so that we can connect your NEO-M8N GPS bought here goo.gl/7Z3gh1 to your Omnibus F4 V2 flight control board goo.gl/bYpmjJ. The wiring colour codes are below in video description, Press SHOW MORE to see the FULL details, Matt
IMPORTANT
=========================
Double and triple check your wiring and if needs be do what I did and wrote the connections down on a piece of paper.
The colours of the wires from the GPS unit are the ones you pay attention to, NOT the colours on the wires from the JST SH connector.
You match the GPS wires to the ordering on the connector on the board. You can see the image I used in this episode here on Banggood goo.gl/ONfVAY
Wire Colour Coding
=========================
Below is the colour coding of the wires on the NEO-M8N GPS unit I bought here goo.gl/7Z3gh1 and this goo.gl/X42CZ8 is the right search on eBay for the 6 pin JST SH 1mm connector.
RED - This is the +5V wire
BLACK - This is the GND wire
WHITE - This is the Rx wire which is connected to Tx on the FC
YELLOW - This is the Tx wire which is connected to Rx on the FC
GREEN - This is the SCL wire (for the compass)
BLUE - This is the SDA wire (for the compass)
Using a Different GPS Unit?
================
If you are using a different GPS unit than this one goo.gl/7Z3gh1, then it's likely that the colour coding is going to be different.
So go very, VERY careful and consult your manual or the manufacturer to confirm the correct wiring.
Further Reading
================
I urge you to take a read of the iNav wiki that can be found here github.com/iNa... and specifically the "Fixed Wing Guide" here github.com/iNa....

Thank you so much for starting this video with the most significant bit of info... red wire may not be positive! Saved me time, frustration and money! Thank you
Dear Matt!Thanks a million for your info video on INav, Omnibus etc. for novices - a great help to understand slowly the works of the items needed for FWD flight controlls. You really give us dummies a hope. Please keep up the good work! /Lúðvíg
Matt - thanks so much for this guide (and your other fantastic guides, too). Your patience in taking us through the weird colour-coding transformed this mind-boggling wiring-up task into a much more straightforward one. Thanks to you, I'm now 80% of the way towards having my little Peng***n ready for inav-guided flight. This will be a major milestone for me because I'm a clumsy old git and need all the help I can get. THANK YOU. Simon
Howdy Simon, glad things are going well :) Matt
I wired the GPS, connected.Flashed INAV enabled GPS/compass. GPS turned blue, but compass RED. Did little bit of research and ran command set i2c_speed = 100KHZ and that had turned it blue.
Aaaaaah, ok. TX and RX need to be switched from the GPS to the FC. Much appreciated, friend. Mine seems to work now. Just gotta do a test flight!
Happy Days!
Thanks Matt, got my F4 v1 board last night and followed your tutorial on wiring it to my gps module. All worky! thanks man!
YAY Nathan!
Just one comment on color coding. It is really simple (1-2 minutes job!) to swap wires and get correct colors in right order.
that's the way i do it all the time. red is ALWAYS vcc and black is GND. so you minimise any chance of issues.
when you bugger a connector its never the same again
I really love this series!
Howdy Joseph, happy days, Matt
Hi Matt, thanks for this series. I have most things working but I am only getting about 10% servo movement in Passthrough mode. Any clues? Also I can not get the GPS compass to work (not that I need it!). I assume that I select GPSNAV from the config page?
hi mat good vid my f4 and gps is on its way. would it not be better to de-pin the connector and put the wires in the right order so red to red n black to black ect
lol i think i have O.C.D lol
Howdy Rob, you could do that. When you realise how SMALL they are, you'll get over the OCD for the right colours and solder them up so you can get flying sooner :D
I re-pin the connectors power and ground HAVE to be the correct colors. A bit of Blu-tack and an Xacto knife blade they are soon changed around.
Matt...The wire colors you provide are not consistent with the GPS you indicate should be purchased from Bang Good. My GPS fails to work...primarily I am unable to follow your video since the wire colors are not identical. Please advise. I am using a Omnibus V2. I cant go any further unless this wiring problem is resolved. Thanks.
Howdy Paul, you'll need to contact banggood and ask for clarification on the wire colour coding if it's changed since the video was made, Matt
Could the 'whatever' color wires from the white plug be simply removed (depressing a clip with a pin, etc) and all swapped to correct input position for plug.....just a nuance to make everything sort of 'look' right.....I've done that before on other plugs...but the little catch/clips sometimes bend too much and lets the wires come out of plug easily.....which may have answered why you din;t mention that.
For the connector it might help to un-pin it and plug it back into the connector so that the wire colors match the GPS wire colors. Then there will be no confusion!
Howdy Shawn, yea that did cross my mind, however when you see how small these connectors are in real life, you think "screw that" and use the wiring diagram instead :) Matt
wire colors are still wrong with some NEO-M8N's. Mine is wired Green TX, Yellow RX, Blue SCL, White SDA. Best to open the M8N and see how it's wired THEN proceed with the video using the color scheme in YOUR M8N
Howdy fella, yea good job we looked at the labels in the video. Matt
Hi! If connect UART1(SBUS), UART3(Magnetometer), UART6(GPS), not have more UART for put ESP8266 to send telemetry.
This board is possible soft UART to enable other UART?
Thanks fot this video.
Howdy Marc, I have no idea on that I'm afraid, Matt
so I have been flying wings/planes with compass on (pixhawk/racer) for nothing ... nice !! thanks
Howdy Vincent, if you have it enabled and it's working, it'll help, but only really necessary for quadcopters as they have unlimited yaw abilities and a compass would come in very helpful for those. If it's not broken, then don't fix it :) Matt
Hi! How are you? Nice job! I have Eachine Wizzard X220s with Flight Controller :BF3.1.5 Omnibus F4 V2, I'm wondering if this mod will work on my F4 V2 (not pro) ... mmm...
Hi mate! The GPS unit you suggest in the link seems to have a power supply voltage 1.65 V to 3.6 V. Now from the diagram you show in your video the GPS port have an output of 5 V. Isn't gonna fry the GPS?? Apparently not, since yours is working perfectly, but how can you explain the difference in voltage? Thanks for the great work you do!
Howdy again, 5V is OK, it has a regulator, see this video ua-cam.com/video/LFkKcOpFo7k/v-deo.html Matt
Hi, well what to say? You are great, I just missed that video explanation. You are doing an impressive job with your channel, you are of great help to all of us! Keep going!
Hi Matt, I have a couple of (simple?) questions for you...
- Is the connector in the GPS rcvr the size needed for the FC board? I assume not, or you could have used it instead of soldering up another one.
- The GPS unit says that it has a max input voltage of 3.6V, but you are connecting it to 5V. Won't that hurt the GPS?
Thanks!
Howdy, see the other comments on the GPS voltages and then see this video ua-cam.com/video/LFkKcOpFo7k/v-deo.html. Also the parts required are in the first two videos of the playlist here ua-cam.com/play/PLgoM4-umzSqd0clW-e_A12yKiOpV--3a2.html
Thanks very much! I am sorry that I missed that other GPS video, I was following the series. Love the videos and the help!
hi Mat, great tutorial! I'm not getting GPS signal. Do you think it is good idea to reverse TX6 and RX6 connections from the GPS module?
I'm wondering the same thing, did you figure it out?
Hi, great video, and wish I had one for my Afro build a few years ago. Is there a lighter gps module? These neo's are a bit heavy for a lightweight build.
Thanks for all your great explanations!
EW
Howdy EW, yea there are other modules, but I am staying with this one for all of my builds as they work so well. Matt
Matthew Ogborne
I'm looking for a 1-2 gram module. Any suggestions?
EW
Hi matt great video's I bought a FLIGHT CONTROLLER F405-OSD but wondering where I can wire in the GPS it's a new board to me bit stuck😕
Howdy Pete, I;m sure you can, look for the same UART ports as mentioned in the video, but for your board setup, Matt
Could you explain how connect that module to betaflight f4 pro v3 ? Because I seen videos where people adding resistors into that GPS
Goodnight. I understand that connecting a GPS with a compass to the racing drone could keep it still on a place?
Thanks
Howdy fella, I guess, so I don't fly quads though, Matt
Matt---good man!
Cheers starsky 😀
Matt. Need a bit of help, Got my GPS working problem, and Ive got the compass wired right, but Inav 1.8 wont recognise it. Any ideas?
Gteate video :)
Plug conected.
Saludos desde México.
sorry matt..stupid question...why do you use 6 wires with SLC/SDA if you not gonna use the MAG ... 4 wires should be plenty and a GPS without compass cheaper eur 10 on Bangoog instread of eur 19 with GPS + compass unit ... correcto amigo ?
Howdy Vincent, yea this question has come up numerous times before. That GPS unit I have had fantastic success and for this series I am staying with what i know to work exceptionally well. Also we're soldering up the Mag (compass) at the same time because if you want to enable it, you can do at a later time. Matt
5v? Isnt it supposed to be 3v? I bought exactly the same one from Bangood as in the link. If you follow the link, it says 3v in the specs of the GPS. Can it also handle 5v? Ps: great videos, just subscribed, and will make sure i use the affiliate links, as i get heaps of stuff from Bangood.
Mik H See the playlist/other comments as this has already been proven incorrect or to the point it does not matter because of the use of a voltage regulator, Matt
Awesome thanks Matt.
Hello! So I have a SP RACING F3 that doesn't come with a Barometer nor a Magnetometer, and I have a single I2C port with one SDA connector (that has a wire coming out of it) and I need to connect the above two sensors and a GPS along the same SDA wire. So if I solder it in parallel to the SDA wire, will it work?
Howdy Sam, I have no idea on that board I'm afraid. Matt
Any way to get both GPS and RSSI to work on a Omnibus F4? I have Omnibus F4 with X4rSB receiver. It works great as a racing quad in Betaflight. RSSI is going into CH6. I want to convert it to a GPS quad with iNav but the RSSI is going to CH6 and that is where the GPS input would go. SCL and SCA are combined with RX3/TX3 so I can't use that for RSSI. TX1/RX1 is the same as SBUS, right? so can't be used.
Howdy fella, yea I use RSSI and GPS on all mine where we have RSSI out from the receiver. As for the X4RSB receiver, no idea never used it. Also the RSSI doesn't got to a TX/RX input, it's on a dedicated pad or pin, see the later video on this, Matt
Sir Good Morning I have the Ominibus F4 V3 in which I am connecting my transmitter Flysky i6 to ppm, please tell me how will the GPS wiring on this flight controller board when we do the ppm, you can connect to Sbus But how will the GPS be wired? But the GPS wiring on connecting through PPM can be described as Sir I AM Lalit Singh from India (I am use M7 gps)
Howdy fella, see the other video on the V3 board, you may have a tab you need to solder to tell the board to use PPM rather than SBUS,. If that is already working, then follow the steps for the GPS as they should be the same if using SBUS or PPM. If you get stuck, see the iNav FaceBook group or the wiki, Matt
Hello my friend can i use beta flight f3 osd with that gps thanks.
matt i need that port for ibus .. can i put the gps on another port ?
Please help me, I am trying to put a cc3d into an X8 Sky Surfer X8, the receiver's connection to the cc3d is PPM, the servo of the elevator I turn on channel 3 of the cc3d, servo rudder on channel 6 of cc3d, right aileron no 5 and left aileron no 4, only the left aileron works, the right aileron connected to port 5 of cc3d does not work, if it puts it in port 4 it works, then I conclude that the servos are ok, the same problem is in cc3d, I have two here with me and both are giving me the same problem, do not work the aileron of port 5, have any way to solve this?
Howdy Christian, I;'m afraid I have no idea for a CC3D. Also that board and the Naze32 are no longer being supported by iNav. Matt
Does the FC from Banggood come with them pigtails?
Howdy, if you see the video, you need to solder them on and they are bought separately. See part #2 in the series. Hope that helps, Matt
on this board for Inav users : on port tab only open : GPS on UART6 (no need to open port for the mag..I was doing that and messing everything ) ...on configuration tap GPS: enable, Ublox, auto detect ... on configuration tap sensors : select mag HCM5883 (most commun) auto for me was not working and u r good to go...
Howdy Vincent, we don't need the mag for fixed wing models, they're always flying forwards so the GPS fix is more than adequate, Matt
Hi Matt,
I can't find the link to the connector? has it been changed or removed?
Morning Nick, see here goo.gl/X42CZ8 and I've updated the description too, thank Nick!
Awesome!! Cheers Matt
Is there a circuit diagram available for the Omnibus F4 V2?
Howdy Nick, yes, ask the company that you bought it from as they all vary slightly, Matt
Thanks
What if my GPS has no compass only has 4 wire? Which is only has red, black, rx and TX?
Hey Van, as mentioned in the video, you find out which wires do what and then connect those up. A compass is not needed for fixed wing models, Matt
RagTheNutsOff thanks Matt , I just hookup the gps without compass and it works . Appreciate your help
Happy days :)
Where i can buy the connector that going into the fc from gps?
The original from gps is not working. It didnt match
Hi Tian, see part 2 of the series, Matt
Can you guide for omnibus f4 v3
Hi, isn't there a plug in play GPS unit that works with this?
Hi Majid, I wish there was as it would save soldering up the connectors, Matt
Sorry matt I can't find that other video ummmmmmm I found this one which is more us full as the other video you gave me was for the v1 board, I have a v2 board f4 so the other video is erelevent how ever on this video you have that cable and plug, where did you get that from please, As I said the plug that comes with the GPS unit will not fit my f4 board. It fisicly won't go in.......... plus you have 6 wires in yours where as mine has 4 pluss the other 2 for the sli, and what ever?
Howdy Nigel, see video 2 in the series, you need a 6 pin JST SH 1mm plug/wires, Matt
If you have a chinese m8n gps module with compass, the one without the blue wire. Then Tx is green and Rx is yellow. May you save precious time that I have lost.
Muito bom
It's a mag-ne-tom-eter....not a mag-nom-eter. Great videos though. Thanks.
my gps does not have the blue wire, instead its orange. wtaf
Take the back off, it's written in the board what they are. Matt
@@RagTheNutsOff you're a star Matt, great idea, I will remove the gps cover to check the wires.
Plenty of detail for the inexperienced. If you go wrong with this chap, you have only yourself to blame.
