eljuli Posted November 9, 2021 Share Posted November 9, 2021 Hi I have this programmer and broke the 3.3v terminal pin so i'm not able to power the board. unless i can solder somewhere a wire to power the board from vref signal that is the same voltage... but there is not schematics so can't solve it without your help. Where should I find a place or info to solve this problem?. just need to know a place where to feed the 3.3v not the whole schematics. Thanks, regards.

0 JColvin Posted November 9, 2021 Share Posted November 9, 2021 Hi @eljuli, Could you attach a picture of your module? I'm not understanding what you mean by broke the 3.3V terminal pin; do you mean the pin 11 pad, Vdd, has been completely removed from the board? This will also help give us a better idea of what options are available to you. Thanks, JColvin Link to comment Share on other sites More sharing options...
0 eljuli Posted November 10, 2021 Author Share Posted November 10, 2021 Hello, thanks for reply. i'll try to explain a bit. I soldered some pins to the board(I know this is not the purpose of this board but this is what I have) to program an external fpga board. the problem is the pad for the 3.3v pin was tear apart so now I don't have a pad to solder a pin and power the board. see attached: I have vdd pad intact so I guess I can use this pin to feed the 3.3v but if not I can manage to use an extra 3.3v source...

0 JColvin Posted November 10, 2021 Share Posted November 10, 2021 Hi @eljuli, I asked one of our design engineers about this and they provided a couple of alternate options, circled in blue, for where you could provide a 3.3V supply. They mentioned that the connection point on C13 would probably be best tie-in point based on physical size alone. Thanks, JColvin Link to comment Share on other sites More sharing options...

Question
eljuli
Hi I have this programmer and broke the 3.3v terminal pin so i'm not able to power the board.
unless i can solder somewhere a wire to power the board from vref signal that is the same voltage...
but there is not schematics so can't solve it without your help.
Where should I find a place or info to solve this problem?. just need to know a place where to feed the 3.3v not the whole schematics.
Thanks,
