I am currently working on a project where I am powering the TX2 over ethernet and trying to get multiple USB 3.0 cameras to run off the board. I am currently using the developer module to do this equipped with a cheap 4-port USB 3.0 “Data Hub”. With a voltmeter I have been looking at the current being delivered to the TX2 as I plug in the 3 x USB cameras. Each camera seems to add 2.3W. The issue arrives when I plug the third USB camera in. The current hops around and it seems that there is an issue with the USB hub delivering enough power to the cameras.
Is there a carrier board with multiple USB 3.0 ports so that I wouldn’t have to plug everything into a cheap USB hub?
If not, is there a better way of going about this?
What is the best way of getting a microphone hooked up to the TX2?
