Let me write my concern about your update. It seems that Jetson Nano Dev.kit does not contain PoE circuits on the board and as for Raspberry Pi, it needs for additional mezonin board a.k.a. PoE-hat, which transforms PoE supply to Jetson needed 5V supply and provides it via GPIO header, does it?

Great idea with the colour coding, been using electrical tape to colour code allen keys and spanners for a long time, but never thought to use it for power supplies.

@@Neomanee For the Raspberry Pi POE hats, the power is limited to 2.5A @ 5V. POE is 48V, so it needs conversion to 5V. However it is with asking in the Jetson Nano forum as to what the maximum power that the Nano can accept through the POE pins. Thanks for watching!
You're welcome. At the time of the video, I had just succeeded in getting the RealSense cameras to work. There's still a bunch of work left I'm afraid, including video display optimization. At the same time, camera to glass latency is higher than normal cameras, because they process the images before sending them. It also doesn't help that the images need to be scaled before they are displayed. When you have 3-4 streams coming in at 30 fps, it just takes a while to get it on the screen. Typically that's not the way these cameras are used, the output streams are usually processed by an application (for things like depth sensing, occupancy mapping, SLAM) and are not displayed as a video stream on this level of machine. Thanks for watching!
how do we get realsense cameras to work?? the realsense github repo show that it doesn't support kernel 4.9. please show us how? many people with nano and realsense are stuck.
Hi. Is there a fifth way and if so would you do a video please? What's the fifth way - battery. Ok not exactly a fifth way because you would need to use one of the standard ways to power. I am enjoying the videos and wonder if this is the sort of power that gives you the option of running this as your daily rig. Keep up the good work as you unveil the hacks you can do with the Jetson. If the jumper doesn't jump, is it worth using it to keep you warm?
This is a very broad area without some type of application in mind. It can range from connecting connecting a 5V power bank (such as: amzn.to/2XkbWi0 ) via microUSB to much more complicated setups using very large batteries and voltage converters/buck converters. Thanks for watching!
It should be. This question is worth asking on the official NVIDIA Jetson forums, where a large group of developers and NVIDIA engineers share their experience.
Batteries are a lot trickier, because power draw, battery selection and application make a difference. If you plug it into the wall, it's easy to make a selection. With a battery, there's a bunch of tradeoffs. For example, two of the NVIDIA robots that were introduced at GTC use a Nano ( ua-cam.com/video/X3qGDYie1_I/v-deo.html ) The JetBot uses the USB port and runs in 5W mode. This is really cool because you can use an inexpensive 5V power bank, and all you have to do is plug in a regular USB charging cable. In general, power banks don't deliver 4A, they are usually less than 3. For more current, most batteries are at higher voltages. Which means you have to step down using a buck converter or voltage regulator. For example, the Kaya uses a 20V DeWalt battery (from a drill) and a step down regulator. You have to do some wiring and such to get everything to work. Of course, since it's a system that means it all plays together, you need a bigger battery for more power, the higher power draw means that the batteries don't last as long, the batteries weigh more which matters if it's on a robot and is mobile, and so on. It's a little different game in that there's no 'obvious' solution. Thanks for watching!
On a Jetson Nano B01 (the one with two camera connectors), you short pins 5 and 6 of J50. J50 is located on the carrier board directly underneath the SD card on the Jetson module. Typically people will put some type of momentary switch there. Thanks for watching!

hi, thanks for all this videos showing excellent material! Do you know an adapter for PoE connector? Im using some RaspberryPIs w/PoE and I want to connect a Jetson Nano w/PoE, any idea about an adapter to use with? thanks

Typically you would use a buck convert/voltage regulator of some sort. While it is straightforward, it is not trivial and if you are using a LiPo there are added safety precautions with which you should be aware. Heat dissipation is another area with which to be familiar. The answer to this question is more than can be written in a UA-cam comment, please ask this question in the official NVIDIA Jetson Nano developers forum where a large group of NVIDIA engineers and Jetson developers share their experience.

Hey Jim! Nice video as always! Is barrel jack maximum power draw 4000mAh ~ 4a at 5v? I wonder how would Nano perform with microUSB power without an attached monitor. It can't draw more than 2amps through microusb, right? My Nano just arrived Brazil today, I'm receiving it home in a couple days. Cheers!
Thank you for the kind words. I'm not sure what the tolerance is for the current draw. My guess is that it's a within the specs +- 10%, but that's just a guess on the 2A and 4A. The power draw issue isn't just the monitor, it's the combined draw of the Jetson module plus all the peripherals (mouse, keyboard, cameras, USB devices like USB drives, SSDs and so on), and anything attached to the GPIO pins. Thanks for watching!

No I don't. However, you should be able to connect your power source directly to the GPIO header using standard Dupont connectors. You'll probably want to make sure the power source is well regulated, a 5V. If you want to be sure, you should ask on the official NVIDIA Jetson Nano developer forum, where a large group of developers and NVIDIA engineers share their experience. Thanks for watching!
@@JetsonHacks yep, was really easy. I use to outputs from Xiaomi power bank and just connected it to 2-4 for 5V and 6-9 for GND. Thanks for your reply.
Ì do not understand the video. Is there any different to power it with micro USB connector or the Barrel Jack if both have 5v 3A =15W? will it go slower with the micro USB then?
The maximum current the Jetson can draw from the micro USB connector is 2A. The maximum barrel jack draw is 4A. Not sure what your point is about in using 3A in both cases.
@@JetsonHacks ok, so if the Jetson nano need more than 2amp will it slow down the CPU speed or will it shot down when I power it with my 3amp power connected to the micro USB?
That works if you have the right sized connector. 2.1mm ID, 5.5 mm OD, center positive. Note that the board can draw up to 4A. Which means that you may have situations where the board is trying to draw more than 3A. This might be from a combination of Jetson power draw and peripheral draw. For example, an additional power hungry USB device or two. Thanks for watching!
Hi Jim, my Jetson Nano is shutting down when I try to run camera and Lidar both. I have connected with Lipo battery of 4A, 2200mah,11V and 14.43Wh. I'm using buck converter to step down(4A, 5V) the voltage. If I unplug Lidar then it's working fine but shutting down if both connected. And I'm also able to run both with 5V, 4A adapter. Can you tell me where the problem is? Thank you so much. :)
I do not know where the problem is. However, it seems unlikely that your battery solution is actually providing 4A. A buck converter, while efficient, will still cause some power loss (usually a little >10%). Also, the claim that the 2200mAh battery provides 4A seems odd. If the battery is 1C, you would expect 2.2A, if 2C you would expect 4.4A. Sometimes the manufacturers fib a little, or the battery might be a little older and not provide that much current.
@@ansjaved3484 I don't have any suggestions, it depends on the application. Please ask your question on the official NVIDIA Jetson Nano forums, where a large group of developers and NVIDIA engineers share their experience.
Mr. Fire Extinguisher is one of the stars of the channel. When I was in high school, my chemistry teacher told me "The way you do experiments, you should keep a fire extinguisher beside you at all times." I found out that he was not wrong. Thanks for watching!
Thank you very much for this video. My Jetson Nano was working Well till the last night. When I turn on my Jetson Nano today, the green LED light is on for 1 second and gets off automatically. But if I do not insert the SD Card, then the LED is Continuously ON, I don’t know what happened Suddenly. I thought this is due to SD Card Corruption. So I formatted SD Card, I again flashed Jetpack 4.4 Image on to my 64GB SD Card. If I insert SD Card again the same thing. Kindly help me to resolve this issue. Would be a great help.
Sigh. For a 2019 device, why not USB-PD? Using USB-C interface with 30W easily. No over-voltage, no "magic smoke" Alternatively, there is a RJ45 interface, why not use PoE? Than can go up to 45W or 29W modes Cheap and lazy designer of the board.
The Jetson Nano Developer Kit has a PoE header ( J38 ). That header passes through the high-voltage 48V PoE supply from the Ethernet port so that it can be stepped-down or regulated by 5V PoE hat or voltage regulator. This regulated 5V supply can then be passed to the 5V input pins on the 40-pin header. An example PoE hat that can do this automatically is here: amzn.to/2GqmvL6 It will take the 48V high-voltage from the header, step it down to 5V, and pass it back to the 40-pin header. It can be mounted on top of the Nano devkit. Or you can do this manually by wiring in your own 48V->5V regulator. Does this not meet your needs?
Close enough for the time being. If the board can be powered by PoE (rated length of cable to be 100m but recommended to max 90m) at least it is better than using USB power which has limited range (3m if I remember correctly) or the power brick which is 1-2 m max from a power point as well. However, the one you suggested only output up to 5V/2.5A = 12.5 W, still lower than the barrel jack. So greater range + convenience (if you have PoE) - price (as not everyone can get access to a PoE switch which is more expensive than a 30W USB-C PD charger) - vs more power & shorter range. That said the next version of the board should just eliminate the barrel jack and upgrade the USB interface to support USB-PD as the sole reason for the barrel jack is an obsolete interface to provide more power to the system. As seen from the many comments below, there is a request for USB-PD. In both cases of USB-PD and/or bult-in PoE support, the board can accept more than 25W which would greatly expand its capacity to support more demanding chips etc.
Thank you for taking the time to comment. As you know, the Dev Kit consists of two parts. The Jetson Nano module, and a carrier board. There are several companies that are working on bringing different configurations of carrier boards to market, perhaps those will better fit peoples needs.

I'm using buck converter to step down(4A, 5V) the voltage. If I unplug Lidar then it's working fine but shutting down if both connected. And I'm also able to run both with 5V, 4A adapter. Can you tell me where the problem is? Thank you so much. :)
I do not know where the problem is. However, it seems unlikely that your battery solution is actually providing 4A. A buck converter, while efficient, will still cause some power loss (usually a little >10%). Also, the claim that the 2200mAh battery provides 4A seems odd. If the battery is 1C, you would expect 2.2A, if 2C you would expect 4.4A. Sometimes the manufacturers fib a little, or the battery might be a little older and not provide that much current.
@@JetsonHacks Can you suggest me any suitable battery?
@@ansjaved3484 I don't have any suggestions, it depends on the application. Please ask your question on the official NVIDIA Jetson Nano forums, where a large group of developers and NVIDIA engineers share their experience.
what do you think about adapter 5v 8 Amp?? or 5v 6Amp
The Nano can only draw 4A, so whatever you feel comfortable with. Thanks for watching!
Can we use 12 V 2 Amp?
I couldn’t find 5V 4 Amp anywhere?
The Jetson Nano is designed for use with 5V. If you use 12V, you may damage the device.
Good tutorial, does jetson nano support microsoft kinect 2 ?
People have gotten it running on the Jetson TX1, I'm not sure what changes would be needed to use it with the Nano. Thanks for watching!
Can you list the cameras' part numbers?
As stated in the video, Intel RealSense D435i and Intel RealSense T265.
Never steal jumpers!
Yes! Stealing is wrong! Thanks for watching!
Does it come with the jumper though? nvm...can I just short them...
No, you need to supply it yourself. Thanks for watching!
Why do you have the extinguisher? Do I need that one?
Mr. Fire Extinguisher is one of the stars of the channel. When I was in high school, my chemistry teacher told me "The way you do experiments, you should keep a fire extinguisher beside you at all times." I found out that he was not wrong. Thanks for watching!
@@JetsonHacks :D - Thanks!
I wondering why the fire extinguisher was there as well.
Put behind the screen like imac so ........................
Thank you very much for this video.
My Jetson Nano was working Well till the last night. When I turn on my Jetson Nano today, the green LED light is on for 1 second and gets off automatically. But if I do not insert the SD Card, then the LED is Continuously ON, I don’t know what happened Suddenly. I thought this is due to SD Card Corruption. So I formatted SD Card, I again flashed Jetpack 4.4 Image on to my 64GB SD Card. If I insert SD Card again the same thing.
Kindly help me to resolve this issue. Would be a great help.
Please ask this question on the official NVIDIA Jetson Nano forum, where a large group of developers and NVIDIA engineers share their experience.
How can I do video stream over the network in jetson nano??
Nano power management is pretty bad. It can't even boot with my 5200mAh power bank. Raspberry Pi 3 is working on it up to 5 hours with SDR USB dongle.
Hi. Is it possible to mine crypto on Jetson?
Sure, if you don't mind losing money. Thanks for watching!
Sigh. For a 2019 device, why not USB-PD? Using USB-C interface with 30W easily. No over-voltage, no "magic smoke" Alternatively, there is a RJ45 interface, why not use PoE? Than can go up to 45W or 29W modes Cheap and lazy designer of the board.
The Jetson Nano Developer Kit has a PoE header ( J38 ). That header passes through the high-voltage 48V PoE supply from the Ethernet port so that it can be stepped-down or regulated by 5V PoE hat or voltage regulator. This regulated 5V supply can then be passed to the 5V input pins on the 40-pin header.
An example PoE hat that can do this automatically is here: amzn.to/2GqmvL6
It will take the 48V high-voltage from the header, step it down to 5V, and pass it back to the 40-pin header. It can be mounted on top of the Nano devkit. Or you can do this manually by wiring in your own 48V->5V regulator. Does this not meet your needs?
Close enough for the time being. If the board can be powered by PoE (rated length of cable to be 100m but recommended to max 90m) at least it is better than using USB power which has limited range (3m if I remember correctly) or the power brick which is 1-2 m max from a power point as well. However, the one you suggested only output up to 5V/2.5A = 12.5 W, still lower than the barrel jack. So greater range + convenience (if you have PoE) - price (as not everyone can get access to a PoE switch which is more expensive than a 30W USB-C PD charger) - vs more power & shorter range.
That said the next version of the board should just eliminate the barrel jack and upgrade the USB interface to support USB-PD as the sole reason for the barrel jack is an obsolete interface to provide more power to the system. As seen from the many comments below, there is a request for USB-PD.
In both cases of USB-PD and/or bult-in PoE support, the board can accept more than 25W which would greatly expand its capacity to support more demanding chips etc.
Thank you for taking the time to comment. As you know, the Dev Kit consists of two parts. The Jetson Nano module, and a carrier board. There are several companies that are working on bringing different configurations of carrier boards to market, perhaps those will better fit peoples needs.
Agreed. As long as there are alternatives then that would work. Hopefully Nvidia's next carrier board is more up to date.
