My team is currently using a Jetson Nano plugged in to the radio via Ethernet for vision processing. We would also like to add a LED controller to our robot, and our current solution is to use a Arduino with Ethernet Shield. Both would communicate with the RoboRio via UDP over ethernet. (We want to keep the USB-B port on the rio free for tethered testing during competition)
But, there are only two ethernet ports on the radio, and one of them is connected to the RoboRio. What’s the best way to go for implementing two onboard controllers? Would a ethernet splitter work for this application?
