hi, Can someone tell me if i always have to leave out the led limiting resistor on the pcb and jump the connections if i put the LED on the 3PDT board?
thx
Depends on what build you are doing. In general you can just leave the LED and limiting resistor off the main board, don't jumper them. Just leave them empty.
But let us know what you are actually building, it might be an exception to the rule.
