Hi Xiaonfan, Because the board has already been etched with the pins floating The board is a prototype anyway so this can be adjusted at some stage latter. Is it OK to tie them both to GND ? This I can do with the prototype board without to any issues, however connecting them to Vdd and Vss would be a problem especially given the 0.4 pitch. If they are left as is - ie floating, what sort of issues can I expect ?
