- This video shows the analysis and reverse engineering of an electronic assembly which was supposed to be inside a Ukrainian "Stugna-P" missile launcher.
One board contains an Atmel ATMEGA168 micro-controller which is connected to a MEMS rate gyroscope and one MEMS accelerometer. The gyroscope is soldered on a small pcb which is mounted on a small mechanical assembly. The angle of the gyroscope can be adjusted using two screws.
Another board permits the servo control of the position of something linked to a brushless motor.

*Analysis of Military Electronic Boards from Stugna-P Missile Launcher*
This video dissects and analyzes the electronic components found within a suspected Ukrainian Stugna-P missile launcher. The analysis focuses on three main boards and their functionalities:
*Gyro and Accelerometer Processing Board*
* *02:04* - The board houses a MEMS gyroscope (ADXRS453) and a MEMS accelerometer (ADXL1001) for measuring angular velocity and acceleration.
* *02:26* - An Atmel ATmega168 microcontroller processes data from the gyroscope and accelerometer.
* *02:49* - The accelerometer's analog output is connected to the microcontroller's ADC input for conversion to digital data.
* *03:01* - A ribbon cable with a comparator circuit transmits information between this board and another.
*Servo Control Board*
* *03:36* - This board manages the servo control of a brushless motor, possibly for positioning optical components.
* *04:12* - A DAC (Digital-to-Analog Converter) on this board provides voltage input for the servo control loop.
* *08:49* - The MC33035 brushless DC motor controller governs the motor's operation based on input from the DAC and feedback from a potentiometer.
* *10:15* - DAC circuits translate digital position commands into analog voltage signals.
* *11:27* - A summing amplifier combines the feedback voltage and DAC output to generate an error voltage for controlling the motor's speed and direction.
*Interface/DSP/CPU Board*
* *04:45* - This board acts as an interface between other components, containing MOSFETs, optocouplers, and connectors.
* *05:08* - A Texas Instruments TMS320F DSP (Digital Signal Processor) was present on the board, suggesting advanced signal processing capabilities.
* *05:23* - Another unidentified IC was missing from the board, leaving its exact function unknown.

What is it?
Thanks Michel. Keep the military tech videos coming. I love them.
Good to see that the wires pass through the pcb before being soldered. A very simple way to provide the wiring with protection against vibration.
The "FP" logo on the PCB is that of Fastprint, a large Chinese PCB fab.
oh shit. this is bad actually. all military equipment must be produced at home country.
@@ArtyomGalstyan Stugna-p is Ukrainian and pre-dates the war, it is not surprising to see Chinese components in it.
@@zedsdeadbaby Its not so much concern about components, but more of the PCB layout. If the components were also pnp in China, this is a huge issue. They could steal the design. I hope they only printed the PCB.
@@ArtyomGalstyan there is nothing juicy at all from what I can see here? Targeting boards are probably developed somewhere else.
@@ArtyomGalstyanif a russkie says..
We use this in our products Acoem laser alignment ICM-42688-P from TDK. With KALMAN filter you can get very good results. We do signal process in Software ARM CPU
Despite this being well out of my wheelhouse I find your reverse engineering and analysis to be very interesting, although other than driving away the irritating TV licensing inspectors I can;t think of a use for a $20.000 Stugna-P missile system, even with the HE-FRAG option.
However I and others are interested in how you manage to acquire all these military toys'. Any comment on Dassault-Breguet Super Étendard Exocet Air / Ship / Land (1982 hack) ! .... ? Nice Schematics.
merci Michel , toujours super intéressant , bravo pour la retro , encore un grand merci pour le partage c'est a chaque fois un réel plaisir.
Incredible analysis of Stugna-P electronics, Thanks for the video. We ask for more electronics from various rockets and aircraft)
très intéressant a voir, merci!!
this is very cool, i work for a company that uses gyros for downhole drilling navigation, cool to see other implementations of mems gyros
Thanks, very interesting...
The screws are soviet era style slotted head design, while all the components and the pcbs are imported, interesting
Because Stugna-P missiles are not new missiles. These are reassembled missiles of soviet "Castet" (Brass knuckle) ATGM complex installed on T-55/T-62 tanks, with "Sheksna" (Named after a river) and "Bastion" missiles respectively.
Stugna-P uses essentially the same missiles with old, expired components rebuilt and with a new warhead, which shows a bigger bulge because of how HEAT works (That's why her caliber is 130mm and not 100/115). There are no wonders, there is no magic in the world and heroics only get you that far.
Головне що працює, і працює дуже гарно. А обЗирать обозрімоє кожен так може.
под высокотехнологичными блоками с ПЛИС цинк и ксайлинсками и GLONASS из РФ собранными на западных чипах "Русские ничего не могут,смешная электроника, все развалилось"
Под видео с платами местного производства на ATMEGA168 "Зато работает". Убогие людишки ,вы что не смогли стиралки разобрать посовременнее :)?
@@uaz-3163видишь ли, 1) украина не сралась с западом, 2) украина не пыталась играть в совковое "всёсвоё".
You can extract data/code from that Atmel microcontroller =)) we can learn stuff from it.
I'm 99.9975% sure that the Lock-bits are set and you can't read its memory.
@@AlphaAquilaeooooh, not sure, lock bits are set 😂😂
@@AlphaAquilae this can be circumvented.... check out glitching
Is it possible to workaround the lock bits?
@@AccidentalScience of course and it is very easy on such old crappy AVRs.
This part belong to the rocket it self ,not the launcher due to gyro ic's it contain
Interesting. I think I've never seen such a single gate logic component like the NOR gate actually used. But maybe I simply didn't look up every SOT23-5 part I came across...
If they are surprised that if they are going for reliability, that they would connect the accelerometer via an analog signal (2:50). You'd think that a digital bus would be more reliable with EMI.
Might be interesting to see if you can pull the firmware of the atmel chip! Shouldn't be hard to try.
easy to extract the firmware, but what would be the point, there is surely nothing interresting inside.
Cara, o que me deixa perplexo é que depois do desmoronamento soviético a indústria mundial passou a se terceirizar para a China, e muitas empresas fecharam ou terceirizaram sua linha de produção, o que fez dessas empresas reféns do sistema
Great Video ! What schematic capture software do you use in this video ?
I use PADS Logic.
even if you can't pull the firmware, any chance of just probing the UART?
I like the teardown but I'm missing the context. Perhaps a block diagram analysis would help us mere mortals.
Well.... The least to say is that it was inspired by Arduino designs, You could download half of the schematics strait from their forums
Чипы atmel довольно распространены на территории украины ,беларуси и росии много разработчиков сними работает так пошло с 2000 годов
no, you get it the wrong way, Atmega were common parts for engineers who are nowdays in their 50/60, to make Arduino the italians used what was cheap and they knew, crappy Atmel AVRs. The parts you find on this board are not "inspired by arduino", nor hobby grade, these are higher grade accelero and gyro. You also wont find an automotive grade Atmel AVR in Arduino boards...
How do you read the writing on the chips, if they're removed?
Concerning the ATmega168 you can program or read the content of program memory using the SPI bus via the 6-pins connector K2, if the lockbit is not set...
The first Stugna was practically a copy of the Soviet ATGM 9K116 "Brass Knuckles".
Fast Print (FP) mark on pcb , Chinese pcb manufacturing, we have them in our company, not so qualified for military purposes.
You are wrong, Shenzhen fastprints actually serves defense, aerospace and medical.
Will be there a open source port to arduino?
nonsense, this is based on expensive gyro, accelero and automotive Atmega, none of these is used on hobby grade modules, and there would be no point anyway because this is an old design, nowdays we have way more powerful and fast accelero, gyro and IMUs as well as very fast and powerfull ARM MCUs which can run a lot of DSP, there would be absolutely zero point to copy this old design.
@@lo2740in no case have I meant 1:1 copy... Of course it should be moved to more modern parts.if available
Stuhna* missile. The Stugna would be spelled 'стуґна'
Исключительно украинские чипы, никакого импорта.А нет стоп.Это же чипы от ардуино! Лолки.Уровень поделки домашний кружок рукоблудия.
Don't reveal our secrets!!!
Yes, spot on... 😢
The good stuff is in the flash anyway …
Оно не советское?
That technology is at least 30 years behind where the real thing is now and 40 years behind the development military technology is today at R&D
F-22 Raptor is 30 years old technology... fisrt flight 1997
Слава Украине !!!
Wow! Let's be friends?
This is a copy of the Russian ATGM
No, this is an evolution of a SOVIET ATGM. Stop calling soviet russian.
@User, lol Russian-Soviet… Same thing!
@@sheikbombalot5781 no, murican, soviet union included Ukraine and other countries.
