Why do flight controllers for our FPV quads have so many copper pads cluttering them up? Do all of these things even do something important, and what do all the little white letters mean written above them? Today we are going to look at some of the most common, and not so common, solder pads on modern flight controllers to see what they are all about!

Dude, Awesome info for beginners like myself. Subbed.

@superspirofpv 9 месяцев назад

Diatone boards are made this way with a purpose. When there's no text they can make the pads bigger and easier to solder on. I prefer this over really small pads like foxeer boards

@calfolkionized 9 месяцев назад

Very useful vid, thank you Ninja!

@BaconNinjaFPV 9 месяцев назад

you are very welcome :)

@Mupshot 9 месяцев назад

Talking about you @diatone. I always make a doc drawing line from the FC to each peripherals board. This has saved me a couple times virtually wiring it up first

Always a great dept of detail in your videos.. Someone down in the nitty and gritty trenches of FPV is a breath of fresh air brother. Keep going; you're influencing many!

@GhostRyderFPV 9 месяцев назад

Flying too?! Oh Shi.... lol Can't forget to reserve a UART pad, re-assign it as a hi low on a Tx sitch, so 3.3V can be output to your relay trigger, so you can feed straight VBat to your coffee maker. On a switch, of course.

@MCsCreations 9 месяцев назад

I like the idea!

@BaconNinjaFPV 9 месяцев назад

But can I switch that 3.3v over the TX and send vbatt to the coffee maker and a toaster oven full of bacon at the same time?

@GhostRyderFPV 9 месяцев назад

@@BaconNinjaFPV Sir, I would never dare to not calculate for *bacon* first. _I'm not a savage, after all._ Love what you're doin with the SpeedyBee content, production values tops, glad I came across your stuff. May I suggest a "Protocol" video for your channel - that is a Wrath of Khan to this video, to discuss SBus, CRSF, CAN, PPM, SmartAudio, Fork, Knife etc that can be used over these newly described pads? I thought of this when ELRS adopted SBus recently, allowing me to use my ancient Omnibus and Eagletree Vector FC's on planes and quads formerly limited to my Frisbee throwing distance. And I Frisbee like I speel.

@Binkoro 2 месяца назад

I am getting a speedybee F7 V3, which has a CC pad, but my Foxeer analog camera does not have a CC wire coming out of it. Instead l, it has an OSD wire coming out of it. Is that the same thing?

@edrone_ 9 месяцев назад

Luckily Diatone includes the paper wiring diagram for most stacks but I think its inconvenient and makes mistakes easier to make without the pads labeled on the board. Come on Diatone its 2023 please silkscreen your boards with labeled pads! Great video and explanation Bacon 🥓 🤟

@MichaelRogersJesusrules 9 месяцев назад

Hey Bro Bacon thank you for sharing all that as 10 or so months ago i would have known about 3 of them, tthis will be a blessing to new newwbies. happy aussie fathers day as well. finaly im getting better,but my body is trashed for good, oh i broke my 1s vtx on the cam , i am sure its not the camera will buy another full setup as its cheaper in the end..i hit to many things,then repairing for 10th time cut finger with new razor took out all of the wires as well when i jumped so ive just desoldered ~removed all the leftover solder,its clean like near new! (some solder dont mix i found out even if its all 40/60 but different brands)) weird but im just sticking to 1 now ..ok ive yapped enough your usualy asleep on discord so i try make it short here!

@derivas007 9 месяцев назад

great video friend! i have a question you could help me..what numbers uart i need to select for gps on this board?there are nothing about it on the manual..

@flat-earther 9 месяцев назад

in betaflight configurator I have enabled barometer on SpeedyBee F405 v3 running BF 4.4.2 but the barometer icon (that's on the left side of the GPS icon) is blacked out, do you know why is that? BTW also exact same issue with magnetometer.

@fpvtv2222 8 месяцев назад

@baconninja I replaced the flight controller in my meteor 75 with a betafpv 5 amp elrs serial aio flight controller. It feels different. Not as easy to fly. I haven't touched the tuning because I don't know what the hell I'm doing. Any suggestions? Maybe flash meteor 75 pro cli?

@hotkatgotama 7 месяцев назад

How can you figure out how to address the led pad with your radio?

@coreyh.3557 9 месяцев назад

What is the difference between 4v5 and 5v on the FC you were showing and why do they do that? Thanks for your help.

@victordiazsaleh1407 4 месяца назад

4v5 will output 5 volts when you plug in to usb. Great for receiver cuz there is no need to plug in the bat and try out modes etc. Of course it outputs 5v with bat connected as well. Personally I use them for receiver and GPS if I have 2 of them.

@Deep_field 9 месяцев назад

So do you think those Arduino NEO-7M GPS modules would work since they output a wide range of different GPS formats via UART? I've just got a ton of them laying around from past ESP32 projects. This also mades me kinda want to tinker around with LoRa and quads.

@BaconNinjaFPV 9 месяцев назад

hmmmmm, I bet they would! If it were me, I would absolutely give those a tinker and see what I could get going :)

How to do a 8 motor drone

@BaconNinjaFPV 9 месяцев назад

Usually they are what is called an X8 where you have one set of motors above the arms and another set mounted upside down in a pusher configuration directly under them. Lots of high end cinelifters for big productions use that layout since it can tolerate a motor failure without falling out of the sky!

@taatoken 9 месяцев назад

@BaconNinjaFPV 9 месяцев назад

@flat-earther 9 месяцев назад

why does a GPS module have an Rx pad?

@TheSaikek 9 месяцев назад

OK but can I connect my analog vtx to Pavo Pico?

@BaconNinjaFPV 9 месяцев назад

Unfortunately it doesn't look like that will work :( The FC (in the revision 2 of the Pico anyway) doesn't have any pads for Vin or Vout and is missing an OSD chip on board as well. They really designed it to work with HD VTX's that don't run anything through the FC. You can always just wire up an analog cam's video out directly to the video in of an analog VTX though if you don't mind skipping OSD! If you do that, you can still control the analog VTX using SmartAudio or IRCTramp like you would if you were running it any other way.

@lemonsquareFPV 9 месяцев назад

Just as an additional note: If you have/got a camera with voltage sense you will at least be able to have a voltage reading onscreen, which I really like having. Otherwise just put a timer on your transmitter, like we used to do before we had OSD.

@h2o40fpv 9 месяцев назад

Ok right at this moment Im building a drone and I need something to watch I opend utub and there you are I dont even know what is the video about but I saw a FC on the tonenail ok let me watch my boy Bacon Ninja lol lol.

man I love that gate setup! So many possibilities with just 3 of them in that layout. Some pretty sweet flying you are doing there, and especially that dive from top to bottom on the double gate :)

What’s with the giveaway?

@BaconNinjaFPV 9 месяцев назад

welp, round one is done and those winners were announced and notified :) Lots of awesome shipping destinations so far! Round 2 got a little held up since I wound up moving houses a whole lot sooner than I had planned, but that one should drop next week. Round 3 is still sitting in China waiting on shipping...which makes me sad...but as soon as I get those I will schedule that one too!
