It just seems too good to be true that such quality information exists for free on UA-cam. You're an excellent teacher and a great human being for sharing this. Thanks heaps
This is a masterclass video. You have such a clean, ordered understanding of everything. I really enjoy hearing you break down the flight controller into it's different categories (hardware, software) and then breaking it down even more from there.
Aside from designing my own boards + systems, really am enjoying watching your designs too. Very good and clean designs you have, excellent work my friend.
Yeah, it’s dreadful how many of them there are these days... Any favourites of yours you can recommend? For flight control stuff I’ve settled for Molex PicoBlade even though they are quite expensive.
@@PhilsLab My last project is dead simple from electronic point if view, it is more electrical - power distribution box for motorcycle - but it must be very robust, as currents are rather large (up to 10A per consumer, up to 30A total) and environment is very harsh due to vibrations. Typical solution in this area is screw terminals, but I don't like it, as I know how motorcycle engine could unscrew any bolt without locktie. I've looked at Molex MegaFit and alike, but some of such connectors require exotic crimpers to prepare cables and not easy to buy if you have access to simple "electrical" shops and not places like Mouser or DigiKey (for example, no retailers sell MegaFit in my country, you could order them through distributor, but distributor works only with big quantity orders, like 100 of one type minimum, and shipping from DigiKey is about $70 no matter what you buy), and I want to have project as accessible as possible. So, after a long reading of application notes, recommendations and industrial standards, I've sacrifice my wish to have polarized vertical connectors and goes with "good old" Quick Fit tabs. Good quick fit tabs or soldering to PCB are not easy to buy too, but, at least, other part (female connectors to crimp on a cable) could be bought in any Car Parts store, crimper for them is present in any car mechanics shop, and it is type of connectors which are recommended, for example, for USA Aircraft Manufacturers (instead of screw terminals). For small-scale connectors my go-to type is "JST" of different sizes (GH, PA, XA), because there are a lot of cheap but rather good Chinese clones around.
Great video. Please continue the great work. You promised to do the following follow up videos on this design, have you done so yet? 1. Low level hardware design 2. Signal processing 3. Telemetry & messaging protocols 4. State estimation 5. Aircraft Modeling, control system design and implementation 6. Higher level performance design 7. Ground control station design If you have not done so yet, please consider doing them as soon as you possible can. We would be very grateful as your teaching style, design philosophy and methodology are exemplary. Thanks in advance.
This is art! The board just brings a reallyy wide smile on my face. Your teaching style, your knowledge is so precise and deep! Your videos are precious, extremely valuable… thank you so much for the time you put into these videos
Phil, I admire the thorough design flow that you use; it's really top-notch engineering and it radiates experience in the field. I cannot thank you enough for spreading your knowledge. You are educating the next generation of electronics engineers. Thank you!
Phil, thanks so much for all the hard work. A long long time ago and in a galaxy far far away I spent an entire career in the US Marines and most that time was in the aviation side of the house - aircraft maintenance admin and aircraft statistical analysis with the 3rd Marine Aircraft Wing in California. I appreciate your work in fixed wing aviation and the insight you provide in both code and related electronics. I'll do my best to keep up with you.
@@PhilsLab A Video about signal termination or high speed differential signals like Ethernet / USB layout would be great to have, there is very limited information about it online. Your thought process was very organised, easy to follow and understand even for someone relatively new to the field :)
@@PhilsLab I would like to see a video on how all the sensors data are fused and used, the control algorithm of the UAV and how you can make deterministic processing in your control loop. Keep up the work ;)
@@PhilsLab basic to advance would be amazing!! Im currently going back for my EE. And there is next to no classes for circuit design and layout. I watch your videos for most of my kicad help!
Your courses are easily one of the best put together and understandable online courses in ee and I would easily pay over $1k if you did a course on general subject matters. Please consider it.
Fantastic video! I! I’m just in the beginning of my electronic’s learning path and this kind of material greatly helps to structure pieces of knowledge I’ve got around the web. Lots of useful information. Thank you very much, Phil!
Personally I recommend that you .zip up your design file folder before you even order the boards instead of as an afterthought. You will be much less likely to forget this backup if you incorporate its creation several times in your design process. Zip them up early and often; back them up to the cloud, NAS, and/or flashdrive. Then, immediately, change the version number and folder (directory) name. You can always view the design from the .zip. If you don't need the new version, you can always scrap it later.
@@PhilsLab As a noob mechanical engineer who only knows how to use Arduino. I found your content is so potent for me. My goal is to be able to make a professional-grade custom microcontroller PCB and basic power electronics. Thank you so much!!
I I've manufactured a PCB based on your design specifications, but I'm encountering an issue with the MIC26903YJL-TR regulator. Instead of providing the expected output voltage of 5V, it is only supplying 0.12V. I've attempted to resolve the issue by replacing the regulator, but the problem persists, with the output remaining at 0.12V. Could you please offer any suggestions or guidance on how to address this issue?
Thank you! Haha don't worry - you don't want to see what my first boards looked like.. I'm sure you'll be able to make the stuff in this video in no time.
Now i'm curious :D i'm sure i'll get it done, autorouter is always an option, i use eagle (Fusion360) and EasyEDA but still haven't finished a board yet, more the cad person. keep em coming though, the thought process before even touching the software is super informational and clear
Thank you very much for this structured video. It greatly reduced the anxiety I had starting the project but I have a question I would love to ask you Mr. Phil and many other more experienced minds. I have at least 3 years experience in Electronics and have a good deal of knowledge for PCB Design and I also have a partner who has 7 years of Embedded software programming but we plan on taking a project of building an autonomous drone. Do you think it is necessary for one to dive deep into Control theory or one could work with good open source libraries like BetaFlight or others?? Do major companies doing such dive in deep and write the whole libraries for Normalization, Kalman filters and the likes??
First, I really admire your work. Very good you put together no doubt. However, I think two STM32 is an overkill. Especially since one of them is STM32Fxx a dual core which is kind of two cpus in one chip. So I don't understand why you need to have a fully dedicated STM32 for just datafusion of sensor data to find orientation (euler angles). MPU6050 has a dedicated on board cpu that can do datafusion accurately. one main challenge to do data fusion on a microcontroller is the timing and synchronization which will lead to drift and other unexpected issues.
The STM32H7 you used seems like it’s quite powerful enough to handle all of the needs you spoke about without needing a secondary processor unit (F4). Is there a reason you still chose to do this, was it just for more IO?
Hi, Phil. You tested this board? What worries me is: 1. That power and GPS/RF parts are too close? 2. Same as for sensors being too close to Switching power supply/RF part?
Hi there, thank you for your comment. Yes, I tested this board and have not encountered any problems so far. GPS acquires a fix fairly quickly and the sensors are giving the correct readings.
I've just started working on a minimalist (and much cheaper) version of this board, for which I plan on doing a step-by-step guide through the firmware design. From low-level drivers through to state estimation and control system implementation. Is there anything in particular you'd like a focus on?
@@PhilsLab yeah,i was thinking you had about 3x more cpu power than you could ever use. I can't wait to see it. I did a recent project coding an adhrs from a naze32. I fly it on my homebuilt manned glider.
Sorry for the late reply! Yes, at some point I'll go over the - rather simple - messaging protocol I am using. In essence, it's very similar to MavLink but with COBS encoding.
Why is the fast H7 used for the flight controller, whereas the slower F4 is for the sensor and navigation reader? Generating PWM with an F4 is easy, but wouldn't you want a high speed read of the navigation sensors? Unless .. you want to be able to change PWM at a quicker rate .. ? It feels like the H7 should be used for quick response for the navigation and sensor read unit. Or is the PID controller going to be running on the flight control computer for performing stability calculations? I had planned on building something similar in my spare time a few years back, where the navigation system feeds data into a neural network, but other things just ended up getting in the way. Nice project BTW!
Hey Phil, are there other Videos related to this flight controller board ? for example the PID and kalman Filter implementation for this board, written drivers to the IMU and other sensors...?
Thank you very much, Steve! I typically have a library folder for each individual project - which isn't the greatest way of organising it but it works for me. I've recently started making my own global library with parts I commonly use, so may push that to GitHub at some point!
Do you test your components on breadboard or design directly the PCB? Some manufacturers have very poor documentation and wasting a PCB because there is a design issue is not cheap.
found this video while developing my own flight controller got to 1:58 and had to laugh as I'm currently banging my head on my keyboard trying to write an I2C driver
Is it hard to reflow BGA? Do you normally get the parts assembled or DIY? You briefly talked about copper pour, it would be great if you go over mixed-signal design PCB with KiCad. Great videos!
Hello Phil, I'm a complete beginner interested in learning how to design my own circuit board. I feel like this video is too advanced for me. Could you list some resources for people like me or make a video? I want to know basic concepts about the design process, such as design decisions when wiring and selecting components, and coding the relationship between them.
Hello. I love the work you are doing, congrats! I'm quite experienced with Ardupilot and INav and in both, magnetometer for fixed-wing crafts is optional. Actually (well, in INAV at least, I haven't used Ardupilot in quite a while) it is not recommended due to the fact the orientation is always "forward" and the direction can be determined by IMU an GPS. Do you have any other reasons to use it?
Thank you very much! Yes, magnetometers are rarely used in aircraft as they are rather difficult to calibrate and are influenced heavily by any surrounding magnetic fields - especially those generated by the electronics on the board. The positive aspects of a magnetometer are that it has a much higher sample rate and can thus give a more frequently updated estimate of the yaw of the aircraft. Also, GPS units return course heading and not absolute yaw angle from the north bearing. However, using Kalman filters one can actually get an estimate of the yaw angle via the GPS measurements - this is what 'commercial' flight controllers (Ardupilot, etc) will be doing. I chose to incorporate it as I wanted to play around with how magnetometers work, see if I can get reliable estimates from them, and so on. As you have said they are difficult to incorporate reliably into the state estimation scheme - so I tend to avoid putting them on future PCB designs!
I went through the github repository, I like how its arranged well but for the time being, the source codes and all were beyond my technical understandings. Bro I would pay money for the whole course series if there was step by step tutorial in on some online-learning sites like Udemy, or would be very grateful if its free in UA-cam. Would you kindly show me the the way, what sorts of foundations I should make unorder to grasp the content(besides PCB design skill)? Thankyou.
Love your videos, just started viewing them. Q: you waited to get the HW back to start writing drivers... is there a circuit simulator that could be used to start writing the drivers?
Thank you very much! I'm not entirely sure if there are circuit simulators for that sort of thing. However, I know there's definitely some for various types of microcontrollers - not sure about STM's though!
Soldering of CMS components can be done by the PCB manufacturer in a process called SMT assembly. They have a list of components which are available on their website. They charge extra for this service. For other components, you will have to do it yourself. You can buy said components on websites like Farnell or Radiospare if you want something fast (it's expensive to go that route). Or you can carefully import components from China through websites like AliExpress (beware of what you buy on there). Ball grid array components CANNOT be soldered by hand. Small CMS components are also hard to solder without proper equipement.
I think STM saw this design and decided to bring STM32H7x7 dual core family to accomplish realtime capture and control structure for aerial and ground vehicle

They charge extra for this service. For other components, you will have to do it yourself. You can buy said components on websites like Farnell or Radiospare if you want something fast (it's expensive to go that route). Or you can carefully import components from China through websites like AliExpress (beware of what you buy on there). Ball grid array components CANNOT be soldered by hand. Small CMS components are also hard to solder without proper equipement.
Thank you! I had this board made and assembled by PCBWay in China. But I typically have my PCBs made and assembled by JLCPCB these days.
Exactly what i was looking for!!. Very good.
Could you also please let me know if you could guide me on Hobby electronics.
Thank you for your comment!
I'm afraid I only do paid consulting work, so can't offer free guidance other than the videos I provide on my channel.
@@PhilsLab hello Phil. Yes. Let's discuss. Please give me your contact details.
I always wondered how those complicated pcbs are designed, now i know there are monsters like you out there designing them 😆
Haha thanks but there are far more intense designers out there!
I think STM saw this design and decided to bring STM32H7x7 dual core family to accomplish realtime capture and control structure for aerial and ground vehicle
Phil, very nice work. Can you tell me what IDE/Compiler you are using for the development of the STM32 Firmware?
Thank you, Greg! I'm using STM32CubeIDE to program the STM32s. It's free software and pretty much all you need in my eyes.
