[Solved] Determine the value of the missing components
(1/3) > >>
FatMexican:
Any ideas on how to determine the value of the missing components values without removing the other components form a different section (the PCB has four identical sections that control motors.

wraper:
It's obvious that PCB has exactly the same components mirrored on opposite sides (4 copies of the same circuit). Desolder and measure.
MathWizard:
Have you looked up any of the chip's? You might find some datasheet with example circuits, that are the same or similar to your's.

Where are the missing components, what happened ?
FatMexican:
I Email the manufacturer waiting for the replay; hoping to avoid more disordering if possible.

 
fzabkar:
Could the EEW part be a dual MOSFET?
