+
+!!! note
+
+    With this power source option, we recommend setting Jetson Orin Nano in `7W` mode (`sudo nvpmodel -m 1`), as we observed Jetson in `15W` mode shutdown in certain scenarios like suddenly ramping up the motor from 0% to 100% speed or having motors stalled.
+
 ### Camera
 
 You need a camera module with 22pin cable for interfacing to Jetson Orin Nano 8GB Developer Kit carrier board and the appropriate wide field of view for each JetBot.
