Hi,

What types of connectors are usable on the card side for the LCD or the push buttons ?
Is it possible tu buy connectors already made with cables with no crimping needed ?

Any references are welcome :)

Hi,
I do not know if this thread is monitored much, being just a resource list. I suspect your question will have more exposure on the original thread;

Thanks, I've contacted the moderator. Hopefully they will move the list into post one so that I can update it more effectively.

Hi SAC
This thread will become a wonderful resource as Najda matures.
