Power Supply Recommendations

On the 7i96e can you use the same 5v supply to power the board and the mechanical limit/travel switches? Is 5v on twisted pair shielded wire for limits adequate or should I use 12/24v?

You can use 5V for the 7I96 isolated inputs but you will have better noise immunity with 12V or 24V

meanwell got a duo 5V 24V
if you want to get better performance you may need 36V for tb6560 or tb6600
then next is 48V for the real good woodrouter
