Wow. So much to digest. I had no idea they had a Ryzen in this thing. All of this really illustrates the generational gap between Tesla and the incumbent auto manufacturers.
The Ryzen machine handles the infotainment. It's certainly more powerful than many manufacturers would use, but from a practicality standpoint, many drivers might prefer to have CarPlay or Android Auto and that type of system has much lower hardware requirements. Many of the more mission-critical components are much older and likely shared across every Tesla model ever made, a practice that reduces the need to test variations in critical components. Also, Elon Musk has talked up the infotainment system and he expected it to be disassembled. Most infotainment systems never get public hardware teardowns.
@@thedevincrutcher there was some information in a press release that a certain german manufacturer uses the snapdragon 820A in its newest models that are currently on sale. The chip is from 2016, and looks to be horribly underpowered, the system is slow as molasses. But it does have CarPlay and Android Auto.
@@HNedel CarPlay and Android Auto only need to decode h.264 stream from phone USB and send touch commands back to phone. It's a bit more complicated for wireless, but still not outrageous. The requirements for it are quite low, even a single-core ARM chip can do it without dropping frames. And for many users, Android Auto and CarPlay are preferred over the cars built-in system because it's a more consistent experience, especially for those who switch cars. It's fundamentally the same in a rental Altima as in an Audi and there is something to be said for that.
9:39 What can be the so called "repeater two camera" possible usage? Could there be cameras installed at the corners of the cars, inside the turn signal for example, to help city driving to detect traffic when making a left turn without having the front of the car entering into a traffic lane?.
@@maxmyzer9172 There is another in addition to the backup camera. Nothing has been officially said of it, just observed when the prototype was on display
Hopefully those little coin cells don't get run down as long as 12v is available! At least they're socketed. It's interesting they didn't socket the NVME - I figured after all the trouble with the Gen1 MCUs they'd have made that easier to service.
As far as I know, they moved everything that's written regularly to the SD card and only keep the software installation and low-traffic stuff like settings on the hard-wired storage.
Yeah, it was the massive logs that wore down the memory chip, it was a small emmc job, probably not rated for endurance. Wonder what will happen when the sd card eventually wears out, if there will be some notification for the user to go to a service center or something
@@HNedel This computer is certainly accessible to the average person. Looks like you could probably split it apart without damaging it. And when he pulled the SD card out I'm pretty sure it had a name brand on it so it's not some custom SD card. There are high endurance SD cards available. I use one in my dash cam because it sees multiple overwrites continuously. But they do eventually fail. Just glad to see that they made it a replaceable part.

No, that 16 GB microSD card is used for logging other things (the other Teslas have a separate microSD card for the same purposes). The eMMC equivalent is the memory chip that he pointed out as being 256 GB at 5 min 30 sec (the Model 3/Y have 64 GB).
@@android04 but it is a good thing that they have switched to basically a normal SSD which can handle the write cycles a lot better than the eMMC memory.
Thank you for your great and very informative teardowns. It is very interesting to see the technology and the approach Tesla is using in their cars , compared to legacy car manufacturers. Great design. The EMC requirements for this car computer would be crazy having so many different RF signals on the same board.
This is one more reason for the all-metal enclosure. People keep asking why the (expensive) cast/machined/stamped enclosure when it could be plastic. Especially in the EU, where EMC regs are more strict.
6:45 WOW, an off board Realtek Ethernet controller, I never though one of those existed like without being inside a SoC. Never saw one as a discrete chip before.

My requests for more details: 1) Weber Auto Channel (Prof. Kelly from Weber State) assembles whole subsystems on a bench. I wish, you did so, too. So for example, you could take the FSD board, then attach the Ethernet cables, all cameras, GPS antenna, power, and the bus wires to the actor ECUs (steering, e-motor controller). And you could stress that all parking sensors and the radar sensor transmit their data via busses to this board via separate ECUs. 2) You could assemble the whole infotainment system: the PCB you showed and then: wireless and bluetooth antenna, USB-C cable to the glovebox, console USB, the 3 displays, (e-call), autopilot computer, diagnostic connector, power cable, CAN busses and all ECUs, speakers, LTE antenna. 3) You probably know those boards with ECU, sensors, actors, power supply on demonstration boards in automotive schools. Something like that would be nice when you explain the systems, each with their ECUs, sensors, actors and power supply and ground. 4) A bus topology view would be very helpful. You can start with the Tesla specific diagnostic link connector, its pinout and then work your way down to the switches (Ethernet and CAN gateway), then busses (BroadR, Ethernet, CAN busses) and then to the ECUs, their attached sensors and attached actors, and LIN busses.

There are only 2 other channels that I know of, sharing similar in-depth details about Tesla. One is EVTV, which pretty much went South after Jack Rickard passed away, the other one is Damien Maguire. Engineerix is presenting his knowledge in a much easier way to consume by people with less of engineering and electronics skills and knowledge, similar to Weber, but much more in-depth from electronics stand point. J. Kelly himself is more of a mechanic and doesn't have deep understanding of electronics, unlike Engineerix. You can't really compare the two.
Hi, can you please help to understand, how does the redundant power work on the FSD board? -if there is only one 12V battery, where does the second source come from? -is there also dual power also for the non FSD board? -I see that the white and blue connectors on the FSD board to not have the same number of pins, are they really both power supplies?
Curious what their assembly yields look like for each of these boards. Is the re-work the responsibility of the board assembly house, or does tesla do that inhouse. used to repair boards a long time ago.
@Ingineerix, Thanks for your video, what happen if battery coin is dead ? Or SD card is dead ? For sure in the car life battery coin and sd card will dead.
If the SD card fails the only problem will be that logging stops, and you cannot update the software. But it's also easy to swap. The on-board battery is only for keeping the real-time-clock running if the car's power is removed, so it won't really have any noticeable effect if it goes dead. Since the car computer most always has power this battery should go 20 years anyway.
Why would it. It’s inside the vehicle and no other components inside the car are waterproof. No other vehicle for that matter has waterproofing on their electronic components unpleasant it’s outside
It connects to Toolbox3 via gigabit BroadRreach (1000BaseT1), so you need a media converter. There is no SIM card, at least in the US, they use an eSIM.
the only spec sheet i could find on single pair BR-PMA is 100Mbit... i'm curious how 1000Mbit is achieved... is it still PAM3 at 33.3Mhz, with more channels and higher symbol rate? also, probably a dumb question, but, how did you figure out the diag interfaces (micro HDMI/UART on the ryzen, USB-C/HDMI on the autopilot)?
Could be that they have not finilized the conformal coating at their supplier and/or additional components to release the vehicles to customers sooner citing low likelyhood of water damage. Many manufacturers are making shortcuts right now due to constraints in the supply chain.
@@chouky02 Sealing covers and cable-connectors would be good enough with a pressure relief valve and desiccant to take care of altiude- and temperature-changes, pretty much like for a harddrive. Conformal coating would just be an icing on the cake.
Well that's dumb! It should either be placed as high as possible in the car or sealed extremely well and it's neither. Is the compartment under the passenger floor board where it's located sealed to prevent water incursion?
Simple question, why is it water cooled? It's a 45Watt Ryzen. That thing would be Ok with a simple air cooler that would weight maybe 1/25th of that block and be more than good enough.
Keep in mind this is also cooling the Autopilot hardware, and this is inside a car cabin which can almost boil water in cars outside in hot climates. Air cooling is not going to cut it if you want it to be reliable.
hahaha you got super awkward at the end my guy you ended it like 20 times hahahahaha I like the actual technical specifications you went over, would love for you to go deeper with the technicals
They are driving 3 displays and want to support gaming on 2 at once. If you've ever used an in-car touch screen from another manufacturer you will appreciate Tesla's choice here. Personally I don't care about gaming, but the response of the GUI is sure nice!
@@foggs The roughly 50 watts that this system draws on average including the screens (most of the consumption) is nothing really in the scheme of driving the car down the road. That's not even enough energy to even take a mile off the range. To put it another way, the car's pack can run this almost 2000 hours, or almost 3 months!
Is Ingineerix able to restore Supercharging on Flagged vehicles? What is required to restore supercharging on a flagged vehicle? Is it managed from the mothership rather than vehicle side, and could a non flagged module be substituted? More videos when you have time please, so many details I would love to learn about here, that are not covered anywhere else!
Yes, I can restore supercharging on many models after Tesla has turned it off due to salvage status. I have a video that explains how charging works here: th-cam.com/video/0lxxOsLcNQQ/w-d-xo.html
@@Ingineerix Is there a listing anywhere that outlines which modules/models you are able to restore supercharging on, and under what specific conditions? Really are great videos I dont think can be found anywhere else, let alone with the amount of technical detail. Thank you for the reply
Of course it's possible, but you are probably looking at millions of dollars in development cost. If you include autopilot, probably on the order of tens of millions, if not over a hundred million at this point. Got your checkbook?
@@Ingineerix i see , so it wouldn't be possible to move a existing system to a more powerful console ? Ie for example upgrading the hardware of a jeep wrangler from a basic quad to a 16core with a better gpu . Same functionality but better spec
@@DALINKUP Of course it's possible, but at what cost? If you are designing a car computer like Tesla did on this one to be manufactured in the millions of units for many years of production you can afford those one-time engineering costs. You as a Jeep owner cannot afford the engineering costs to re-engineer the whole Jeep infotainment system. It's too big of a project for a "one-off". If Stellantis wouldn't do it in the first place, how can just one guy?
@@Ingineerix i see , i didn't know if it was possible just to transfer a existing system to better hardware . But you've made me aware that it would take development . I thought aslong as your using a existing system / do not try and edit or add to it you're just increasing the hardware's power . Kinda like how some people use Chinese oem parts to upgrade existing systems , As alot of Chinese factories haven't got millions to develop parts . They just make the connectivity universal .

Engineerix is presenting his knowledge in a much easier way to consume by people with less of engineering and electronics skills and knowledge, similar to Weber, but much more in-depth from electronics stand point. J. Kelly himself is more of a mechanic and doesn't have deep understanding of electronics, unlike Engineerix. You can't really compare the two.
Hmm. I think my car have more compute power than my ageing gamer PC.
It’s amazing how they were able to cram so much processing power into such a small package and run everything the Tesla needs from there.
Fantastic, I’d love to know how much RAM various parts of the main computers uses.
Hi, can you please help to understand, how does the redundant power work on the FSD board?
-if there is only one 12V battery, where does the second source come from?
-is there also dual power also for the non FSD board?
-I see that the white and blue connectors on the FSD board to not have the same number of pins, are they really both power supplies?
There is no "FSD board". The only difference is software. The redundant power is the 12v battery and the PCS. (DC-DC supplied by HV)
Curious what their assembly yields look like for each of these boards. Is the re-work the responsibility of the board assembly house, or does tesla do that inhouse. used to repair boards a long time ago.
I am not smart enough to understand it all but its so interesting. Thank you.
@Ingineerix, Thanks for your video, what happen if battery coin is dead ? Or SD card is dead ? For sure in the car life battery coin and sd card will dead.
If the SD card fails the only problem will be that logging stops, and you cannot update the software. But it's also easy to swap. The on-board battery is only for keeping the real-time-clock running if the car's power is removed, so it won't really have any noticeable effect if it goes dead. Since the car computer most always has power this battery should go 20 years anyway.
hello, are you able to point out or explain all the fuses where they're located ?
There are no fuses in the car computer. See my other videos on this topic.
Nice, thanks for sharing.
Does this revision address the eMMC issue. Did they disable the linux subsystem logging?
Cant wait for people to really get to grips with these systems and offer "unofficial" features and cheap unlocking.
Hmm... How much memory is on the APU and how much memory is on the GPU? That would be really interesting...
Shame it’s not water resistant. Anyway thx for these videos.
pretty disappointing its not water proof.
Why would it. It’s inside the vehicle and no other components inside the car are waterproof. No other vehicle for that matter has waterproofing on their electronic components unpleasant it’s outside
They bathe it in an oleophobic coating which helps keep water away
@@jamarforsythe7262 that wouldn’t help at all if the unit is submerged ln water, which can happen since it is mounted beneath the floor mats.
Tnx so much, tell me please, how it connects to toolbox? Show switch sim card?
It connects to Toolbox3 via gigabit BroadRreach (1000BaseT1), so you need a media converter. There is no SIM card, at least in the US, they use an eSIM.
How can I support your channel financially? Do you have a Patreon link or something like that? FMPOV, you do an awesome job.
Thanks! On my channel's "About" page there is a donation link. th-cam.com/users/Ingineerixabout
"Looking at you Chet" lol
the only spec sheet i could find on single pair BR-PMA is 100Mbit... i'm curious how 1000Mbit is achieved... is it still PAM3 at 33.3Mhz, with more channels and higher symbol rate? also, probably a dumb question, but, how did you figure out the diag interfaces (micro HDMI/UART on the ryzen, USB-C/HDMI on the autopilot)?
I'm shocked that this is not a hermetic unit :o
Yes, given the price and the mount location, that would certainly be the more sustainable option.
Could be that they have not finilized the conformal coating at their supplier and/or additional components to release the vehicles to customers sooner citing low likelyhood of water damage. Many manufacturers are making shortcuts right now due to constraints in the supply chain.
@@chouky02 You can always wrap it up in a plastic container, and make the cables tight with 1$ of silicone.
@@chouky02 Sealing covers and cable-connectors would be good enough with a pressure relief valve and desiccant to take care of altiude- and temperature-changes, pretty much like for a harddrive.
Conformal coating would just be an icing on the cake.
Its not a submarine
Well that's dumb! It should either be placed as high as possible in the car or sealed extremely well and it's neither. Is the compartment under the passenger floor board where it's located sealed to prevent water incursion?
Simple question, why is it water cooled? It's a 45Watt Ryzen. That thing would be Ok with a simple air cooler that would weight maybe 1/25th of that block and be more than good enough.
Keep in mind this is also cooling the Autopilot hardware, and this is inside a car cabin which can almost boil water in cars outside in hot climates. Air cooling is not going to cut it if you want it to be reliable.
hahaha you got super awkward at the end my guy you ended it like 20 times hahahahaha I like the actual technical specifications you went over, would love for you to go deeper with the technicals
1:27 makes a good wallpaper 🤷♂️
Ok plz add a high res pic of the ADAS computer 9:15.
If possible... couldn't get proper view ..
Besides for the custom image processors, why do they need such a beefy system, why not something like a Qualcomm SoC?
They are driving 3 displays and want to support gaming on 2 at once. If you've ever used an in-car touch screen from another manufacturer you will appreciate Tesla's choice here. Personally I don't care about gaming, but the response of the GUI is sure nice!
@@Ingineerix seems like a weird design choice when they've gone to so much effort to reduce energy consumption elsewhere
@@foggs The roughly 50 watts that this system draws on average including the screens (most of the consumption) is nothing really in the scheme of driving the car down the road. That's not even enough energy to even take a mile off the range. To put it another way, the car's pack can run this almost 2000 hours, or almost 3 months!
@@Ingineerix fair enough. It better run Crysis though
With model Y getting AMD chip, I’m wondering if it will be possible to upgrade model 3 atom
Thank you.
Question regarding the Boards. are they Multilayered?
Most definitely, Probably 6 minimum.
also two backup batteries on the autopilot board so redundancy there as well
No, these cannot power the system. They are for memory retention.
@@Ingineerix I know :) backup for the clocks not to drive the CPU or car ;)
INB4 Linus adds liquid metal and overclocks this thing somehow.
Is Ingineerix able to restore Supercharging on Flagged vehicles? What is required to restore supercharging on a flagged vehicle? Is it managed from the mothership rather than vehicle side, and could a non flagged module be substituted?
More videos when you have time please, so many details I would love to learn about here, that are not covered anywhere else!
Yes, I can restore supercharging on many models after Tesla has turned it off due to salvage status. I have a video that explains how charging works here: th-cam.com/video/0lxxOsLcNQQ/w-d-xo.html
@@Ingineerix Is there a listing anywhere that outlines which modules/models you are able to restore supercharging on, and under what specific conditions?
Really are great videos I dont think can be found anywhere else, let alone with the amount of technical detail.
Thank you for the reply
Amazing knowledge , Would it be possible to build a custom computer like this that fits into a jeep wrangler ?
Of course it's possible, but you are probably looking at millions of dollars in development cost. If you include autopilot, probably on the order of tens of millions, if not over a hundred million at this point. Got your checkbook?
@@Ingineerix i see , so it wouldn't be possible to move a existing system to a more powerful console ? Ie for example upgrading the hardware of a jeep wrangler from a basic quad to a 16core with a better gpu . Same functionality but better spec
@@DALINKUP Of course it's possible, but at what cost? If you are designing a car computer like Tesla did on this one to be manufactured in the millions of units for many years of production you can afford those one-time engineering costs. You as a Jeep owner cannot afford the engineering costs to re-engineer the whole Jeep infotainment system. It's too big of a project for a "one-off". If Stellantis wouldn't do it in the first place, how can just one guy?
@@Ingineerix i see , i didn't know if it was possible just to transfer a existing system to better hardware . But you've made me aware that it would take development . I thought aslong as your using a existing system / do not try and edit or add to it you're just increasing the hardware's power .
Kinda like how some people use Chinese oem parts to upgrade existing systems , As alot of Chinese factories haven't got millions to develop parts . They just make the connectivity universal . But thank you for the answer
Whar are these 2 circular things on closure? They look like coaxial connectors.
On the top? Coolant connections.
