Maximum Current on the 3.3V Pin

Hi,

i am currently trying to figure out whats the maximum power / current i could get of the 3.3V Pins that are connected to VDD_3V3_SYS . Could someone help me with this?

Regards
Tim

You can get that in the carrier board specification. Jetson Orin Nano Developer Kit Carrier Board Specification

Hi Trumany,

Thanks for the reply, that helped alot. I am trying to work with the 3v3 Bus on the CSI 22 Pin Camera Connector. In the Document you referenced, there is a table (Table 5-3) that defines the Max Current Capabilities of the VDD_3V3_SYS Bus on the Camera Connector as 0.26A. Is this value for both Connectors together or can each Connector supply 0.26A. Furthermore, would it be possible, to draw more current over it, when no other peripherals are connected.

Thanks,
Tim

That’s for each connector. It could be more if no other peripherals, but still, need to pay attention to the power pin capability of each connector. So better not to exceed that.
