Can you show a closer photo of the circled area with more light?

What LEDs are lit on the expansion board if any when it is connected?

Can you describe for us how and what you had connected to the expansion board at the time it failed?

-power from main board (+-) as shown in the photo
-X stepper was conect to driver 1
-extruder stepper was conect to driver 2
-RJ11 cable was conect to can in from main board
nothing else was connect to that board

I did use for cables connectors that I got with the board

The connections sound pretty standard. This may be a case of premature component failure.

When and where did you purchase the board? It may be covered by warranty.

I bought it from "Rav Meimad"
The Israeli reseller on 22.7.21
