Hello, I am making a drone and plan to add a Jetson Orin Nano on top of it.
In order to power the orin nano, I am planning on using a XT30 to XT60 adapter and then a XT60 to Dc barrel jack wire to connect it to the power distribution board. I am using a 4s 6000 mAh battery (14.8V).
Is this safe to do? The ESCs I’m using for my motors are 20A max.
I really don’t want to damage by orin nano but I need an easy way to power it from a power distribution board that is XT30 and also handles 4 motors.
Please help me with this
For Orin nano module only, the power supply voltage is 4.75V ~ 5.25V.
So then would the proposed system above work if I am able to find a way to bring down the voltage from 14.8V to 5V?
Sure for orin nano module, as said, the only requiement of voltage level is 4.75V ~ 5.25V.
Hello,
I was looking through the Jetson Orin Nano DevKit Carrier Board Specifications and noticed that in section 3.9, it says, if used for power, the ethernet port “converts the voltage to 5V-20V that the board needs”. Does this mean 16V is fine for the Jetson Orin Nano?
@Trumany Hello, I found this other post from may where you told a person trying to the same thing as me that the voltage requirement is 5-20V and that if the voltage is constant between 5V and 20V, there is no need for a step down converter. Why was your answer different this time? Has something changed?
Please help me with this.
5-20V is for devkit. 5V is for Orin Nano module.
What is the difference between the two? The box that my device came in says Jetson Orin Nano Developer Kit.
Does this mean I can power the device from the power distribution board without a step down converter as long as the voltage is always between 5 and 20? What about varying amount of current drawn by the motors that use the same power distribution board?
There is a power option mux design on carrier board of devkit in order to provide 5V only to Orin nano module. So you can use a 5-20V supply for devkit.
What’s the “motors”? For external devices, customer should handle the power supply of that.
Hello,
I should have clarified sorry. As I mentioned in my original message, I want to power the Jetson Orin Nano from a power distribution board. This board also supplies power to 4 motors. These motors draw varying amount of current during a flight. So my question is, how would a varying amount of current affect the Jetson device? What is the maximum amount of current it can handle?
Additionally, how can I verify that I am using the devkit?
The max power of Orin nano module is 15W(8GB)/10W(4GB) as you can see in data sheet. Your power board should guarantee that no matter what the motors are.
“how can I verify that I am using the devkit?”
What do you mean? You should check with vendor for such question.
Ok thank you for you help so far.
I just have one last clarification question. For the devkit, what I understand is that as long as the voltage stays between 5V and 20V throughout the usage, the device will be fine. So even if the voltage starts as high as 17V and dips down to around 10V during the use, the Jetson will be fine. Is this correct?
Yes, it is correct. But a stable supply is always preferred.
