I believe I remember that you said while the EZB3 had pull up resistors, the EZB4 will not. Are you going to make some sort of shield that we won't have to worry about it blowing up our sensors? I remember when i built the LEAF robot, I hooked all of the sensors up and blew every single one of them before I realized they needed to have a buffer/pullup conversion before plugging them in to the port. This concerns me. Just want to know exactly where we stand. I really enjoyed just plugging in to the EZB3 and not having to deal with this. Or, maybe I am talking about the 5 to 3.3v converter if the board does not have both.
Hope you understand what I am talking about. Also, I understand that the chip on the EZB4 is easy to blow up if you make ONE mistake on pluging the ports, ie; backwards. Hope you understand my point. At my age, I am sometimes Dislexy. You have a Beautiful product and I don't want to mess it up.
