USE the POWER! - Jetson Nano

[@JetsonHacks]

I lied in the video. There are actually 4 ways to power the Jetson Nano. As mentioned in the video, there is the micro USB connector, the Barrel Jack, and the 5V pins on the GPIO header. There's also what we'll now call "the secret way", powering the Nano using Power Over Ethernet (POE). Many Ethernet camera systems supply power in this manner. Thanks to @Alex Carter for pointing out this blatant lie.

[@aleksandrbelykh4909]

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?

[@JetsonHacks]

@@aleksandrbelykh4909 That is correct. It is pin compatible with the RPi, and requires the same 48V to 5V converter that the RPi does. Thanks for watching!

Looks like there is some pretty bad latency in that setup, is it just the viewer or is it really that bad? Thanks for all of the awesome content!

[@JetsonHacks]

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.

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.

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. :)

[@JetsonHacks]

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.

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!

Can you please do a quick guide for powering it via battery? I was planning to use the USB but now see that's not who I want to be.

[@JetsonHacks]

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 ( kzbin.info/www/bejne/jmTUeHePnspklas ) 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!

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.

[@henson2k]

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.

[@watcherquek263]

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.

[@JetsonHacks]

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?

[@watcherquek263]

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.

[@JetsonHacks]

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.

[@watcherquek263]

Agreed. As long as there are alternatives then that would work. Hopefully Nvidia's next carrier board is more up to date.
