I’m building a drone and planning to place a Nvidia Jetson Orin Nano on it and power it up from the battery. I have a 4s (14.8V) LiPo battery and a Holybro PDB01 power distribution board which i connect to my motors and the battery. My question is, can i connect my Jetson Orin Nano directly to one of the XT30 connectors on my power distribution board (which would correspond to connecting my Jetson directly to my 14.8V LiPo battery)? Since the motors draw too much current, would the power distribution board somehow provide the same amount of current to Jetson and burn it?
Are you using official devkit? If so, please refer to the Orin nano Design Guide and module data sheet in DLC for the info. Basically, the power supply range is 5-20V. Regarding the current, the IDDmax = 5A, the real current depends on your use case.
Yes, i’m using the official devkit. So can i assume that the current going into the Jetson won’t be higher than 5A at all times? Also would the voltage fluctuations from the battery cause any issues?
Yes, the current wont exceed 5A. The supply voltage should be stable at a value in the range of 5-20V.
Does the value of the input voltage matter as long as it is in that range?
Yes, it should be stable.
Doesn’t the carrier board of the Dev Kit has some sort of voltage regulator? Should I still provide stable input voltage to the carrier board?
What do you mean? It is a basic rule that power supply should be stable as possible. That’s to protect components including voltage regulator.
Thank you for the information. I guess i’ll use a buck converter instead of connecting the LiPo battery directly to my carrier board
In general, the LiPo battery output is stable, you can use it directly if the voltage level won’t be out of the range during the whole usage process.
