hmmm
have a box of these and failed xr cards… anyway to use these again as power failure monitering devices (i.e. dummy pingable devices)
Look like lightning hits…
Usualy, this type of dameage results in a board (once functional again), that tends to be FLAKEY !!
There is some hidden damage and it cropps up at the WORST times !!! (Allways)..
Better off holding down a waste container…
Im my humble opinion..
You can try fix this RB
