External 5V for 3HC
-
I recently implemented external 5V power to the 6HC mainboard in our machine, this is inorder to use an emergency stop circuit that cuts power to the motor drivers only, while leaving the logic side up. While performing this operation I forgot about the 3 3HC boards we also have in our system.
Presently they are not connected to any motors we are only using them as inputs.
Is there a way to also provide external 5V to the 3HC boards?

There is currently no provision for supplying a separate 5v source for the 3HC.
