Cuav x7 pro baseboard

Hi
after using the cuav x7 pro successfully for 6 month in a helicopter ( 700 size ) it was stored for almost a year in a dry room with humidity ctrl ( less than 40% ).
Now the USB doesn’t work any more. The device manager doesn’t show any reaction with different USB cables etc ( Win 10 ) . So the connection to MP doesn’t work. I was using as well the cable and PC as when the USB worked. PW-Link connection works via Mobile ( WiFi ) but MP doesn’t…
Further investigation with a scope showed that there is no processor signal - so it seems that the baseboard is dead.

Has anyone had a similar experience ?
Did anyone replace the defective baseboard with the board showed below ?

Would be interested in your expertise…

Thanks
Kind Regards

Hello,

I have a CUAV X7. I used it with V5+ Baseboard without problem before switching to the CUAV CAN PDB.
