I have a problem with the PROBOTIX BOB (PBX-RF RF Isolated CNC Breakout Board).
It seems that one of the 4 "ADUM 1400" (the channel responsible for feedback from the machine to the computer :limit switches home switches...) was damaged.
It heats up and withdraws lot of current from the voltage regulator.
Does any of you know the exact part #?
When searching on Digi-Key I can find many, and don't know which one works here.
