If you have parts from the original board you could solder a 1n4004 diode from the 12v tab to the unburned side of that m4 and then sort out or replace that larger diode in the same way. Not sure if that’s the best way and some of the other guys may have a better solution. Im just thinking a straight forward bypass of their location in order to restore their connections.

From my board it looks like that’s the 12v trace coming from the capacitor burned up between those components
Yeah i think your right
This is the diode and part number.
Here is a clip of the board without the copper layer so you can look at the traces
D6 is the diode that would need to be replaced with a through hole part to complete your trace I think

So it took the tablet and cable to a computer shop, and he tested and had it talking thru the ethernet adapter, so ot works, it just wont communicate to agio for whatever stupid reason.
Yes it shows up.
Ok. It has to be that IP address then. Watch farmer Brian’s YouTube video on udp Ethernet setup for Aio. It’s a year old and some things have advanced on agopen but there’s lots of info in there on setup and the rabbit hole of Ethernet connection. It’s fairly simple once you get it all talking. It took me a week to get it working on my setup bc I was trying to connect to a usb “com” port. It’s a similar connection but totally different data transfer. If your tablet is finding the Ethernet adapter cable then it should be simple as getting the IP address correct. That’s where I had problems. My laptop was throwing a random IP address for my adapter cable. That ipv4 setting in Ethernet properties solved my problem. There is another place if you double click on unidentified Ethernet (your cable connection), go down to ip settings and go into edit. It’ll give you a prompt to manually setup. Try that but it may not let you save it bc it’s not setup on the network side. Your subnet number (third set of numbers) needs to be the same but your host numbers (last numbers in the IP address) can be different as it all on the same subnet.
What does your agio show for you subnet address? If your running a 1 as that then you’ll need to change that on agio side to connect
Is your computer or tablet connected to wifi or internet? it shows 169.254.224.43 with 0 sent and 0 rec. all connections show down also.
That’s a shame. As above, i put an insulator with thermal grease on the heatsink (I did all of my own through seam components). Seems like a short. I know you ran your motor a bit during testing but maybe under load maybe it’s pulling more current than the board can handle? The trace and diode can be placed with a through hole component and wire, but I’d check the expensive bits are still working before putting too much effort in. I have a teensy that is now a header soldering aid after I didn’t check a regulator and smoked it!
I am absolutely gutted.
Ive tested the f9p lights up, the bno085 lights up, the cytron powers up but the teensy no longer flashes orange but the red light comes on when i press the white button on top, could it be goosed or just lost its software.
Im not sure if rebuilding traces is possible for a chap like me🤔 i think 2 components might need replacing to be safe but can only see through hole option for the one
Thanls very much for going to the trouble of finding that. Pretty sure both the components will need replacing. Not too sure im confident enough to rebuid the traces though
Same problem on two PCB. Everything good, just smoke when I enable “drive”. Even no motor plug on the cyton. PCB dead teensy dead. F9p and bno ok. I’m scared to try again, I’m waiting for the PCB standard 4 to have a better luck !
Anyone had any luck complaining to jlcpcb about these problems?
Are your burnt track problems due to poor handling or use of the engine?
Burn with no engine plug. I don’t know what s happened. Just press “drive” on ago and smoke.
I just got started with a standard version aio pcb. By testing the circuit a bit, I discovered that pin 1 and 4 of the amp socket are reversed. So we reverse the 5v and gnd. Has anyone seen this before?
Based on these two boards burning the trace, is this the trace that needs to be bypassed from the cytron to the ampseal or is this a new issue?
Did you boot with your Ethernet Dongle, or just plugged in after powering up windows?
Sometimes its necessary to reboot your laptop after plugging in or change the ip-adress.
I would love to know what caused mine to go up in smoke. And if i can prevent the same thing happening again and to help anyone else would be even better.
