    Hi whyzix, 

    First I want to point out that we have a video on how and why the levels on the ADuM1250 work here:

    How I2C Isolators Work

    So with the ADuM1250, the levels on Side1 and Side2 are different. Side2 is I2C compliant and Side1 is I2C compatible. Side 1 must interface with compliant devices. Communication isn't possible between devices that both have a high Vol.

    Before doing a respin on the board, its possible mechanically to face the ADuM1250 in the other direction. If the ADuM1250 is turned over dead-bug, and the leads bent backwards, it can be soldered down. Does this help with the debugging?
