Hello everyone, how are you?
I know there are several topics around relating to modifying the EZ-Board for use with an external power supply. I just need to check to confirm that I understand correctly before I start modifying the board.
As I understand it, the ports D0 - D14 power is originally supplied by the board, coming from the lead between ports D19 and D0 as shown in the picture below..right?
So, I will have to cut or interupt that lead to isolate those ports from the board's power like so..
Then I will simply need to reastablish power by connecting the leads of the external power supply to the last 2 pins next to port D14, as indicated by the red arrow, correct?
Do I understand all this right?

I could not find a picture showing the bottom side of the board, I hope this representation will do the trick.
Thanks again, I can get back to work.
Kristian.
Thanks for the illustrations btw, i'm going to use them in a how-to for others
I then found this old thread showing how to modify the EZB3 for external power. This would save all the servo ext wires modifications.
My question is there any disadvantage to using the above modification, vs. the servo ext. build?
Has any one performed this modification and how did it work?
Thanks in advance.

Thanks for the response. That is a good question, does the mod only affect the ports D0-D14, as Okidey thought, or does it affect the 5 ports also on the small side of EZB3?
My eyes cannot follow the traces. It would be nice if not all ports were affected.

If I use this trick, the heat will decrease on the board? Mine get very very hot in less than 10 minutes...
