PCB scheme WT724R

[moon_fire]

Hello,
I'm writing here if by any miracle you can get hold of the diagram or guide me so I can look up the board diagram of a Drayton Wiser Hub. The model is called WT724R. I managed to fry part of the plate and unfortunately one component disintegrated. I sent the board to an amateur electronics friend, but he needs the PCB diagram to know which part to put in place.

Alternatively, if someone can take the Hub apart and measure the 2 resistances that are in the center of the PCB would save me some headaches.

I did manage to find on some forum pictures of the board both front or back but to no use.

Thanks
