What burned on my board?
J1394 is a FireWire port, indicating this device likely connects to it.
It seems there are too many pads for a capacitor but not enough for a MOSFET (unless 4-pin ones exist), and even that might be tricky. Probably just some connections will be missing rather than the whole system failing.
It seems like the issue might be with the controller or the FireWire port itself. Plugging in the FireWire header didn’t help, which suggests the problem isn’t with the connection. It looks like FireWire may no longer be supported.
I just inquired with the seller, who admitted to a mistake when he first received the board. Hopefully, no further errors occurred with this item.
It seems unclear what you're referring to, but you're likely okay.
2 pads probably contain a simple component like resistor, cap, or fuse—no digital logic expected, just DMD should work without affecting other parts
