It’s powered from pcbv2 5v out.
I believe the nano only looks for the imu at startup, so if it isn’t visable to it then, it won’t keep looking for it. I had similar issue but in reverse, i.e. if powered by usb, the nano wouldn’t necessarily see the imu, but if powered up externally before plugging in the usb it works ok. The solution would be to configure specifically for your imu, and make the nano keep looking until it’s found. I’m not sure if this issue is potentially shared with Panda.
I’ll play with the ino then I guess. Thanks for your reply
Legend!!!
Added a 2 second delay in the void setup at the start and it’s working fine. Thanks
I have the same problem, can you tell me where exactly I have to change it.

Just add
delay(2000);
Right underneath the { in void setup
It works now. Thanks very much 
As someone who is just starting into this project (gps/rtk/autosteer) should I be holding off until the UDP and single/multiple boards decisions get decided? I haven’t ordered any hardware yet so it would be easy to delay. Or will this process take 6 months+ so I’m better to move ahead with usb builds V5.5 and figure out changing to UDP later?
Sorry if this is a ridiculous question. I’m so new I don’t know what I don’t know.
Build a UDP capable V2 or Kapoui, for V5.5 if you are just starting. The board is basically a input output card, it will not go obsolete. Most of the magic happens in the tablet.
Not ridiculous at all, started building AOG at the tail end of v4, did not actually get it on a tractor till v5. Now I am hooked.

Is that switch powered? If so, how many Volts? I can’t see anything in the spec.
Switches are always powered, this one comes with a 5V adapter 0,6A. Typical power consumption would be < 1 Watt.
If this is what you’re talking about, it says 9 volts, but if hacked from inside the device, it will also work with 5 volts.
Will it handle a couple of esp32 cams as well or will that slow the auto steer system down? I was seeding today and thought a couple of wireless cameras would be good
Can you power this switch from USB or do you need power from tractor?
You can buy a switch that does either usb or tractor power.

I use this one it takes 12-50v direct, outdoor rated, but you have to remember to flip the legacy switch to turn off poe.
But any switch will do, and haven’t really seen any others fail under normal circumstances.
Even one like this
Could be powered up with this

What kind of PoE options? Can it output PoE?
Wanted that option to try future camera equipment. It says it can, but I have not tried it yet.
Got too caught up, and still in PANDA-mania.
It has a nice sturdy metal case, and runs good off 13.8v with screw terminals as well.
This TP-link SG105 says that is should work with 5VDC so I think you could use it from USB. But does anyone know the size of the power plug so I could order right wire for that?
