Not sure whether board is fried



Hi, I installed Can on the SB2040, everything reports correctly except for my TAP :
The LED on the tap board is red when down and blue when up. So no issues there.
I soldered the opto-TAP board for 5V and had it originally installed on the 3-pin connector with the 5V and gpio28

I later found out that's not the way to do it and moved signal and ground to gpio25, leaving the 5V as is.

Since it's not working anymore I wondered : did I fry my SB2040 ?
