    Potential voltage confliction while stacking two CYUSB3KIT-003 - Part II


      Sorry about the late response, now the old post can not be replied.


      What about a new solution: remove 5V jumper J3 for both CYUSB3KIT-003, and wire out from both board's J3-pin2 and GND and connect to one common external 5V power source. And cut pins as described by "001-87216_AN87216_Designing_a_GPIF_II_Master_Interface.pdf". Then no problem can happen anymore, both board are supplied by the same power source at the same time. This give another benefit - easy to power cycle the two board at the same time.
