Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Ok, a question to Olimex guys.
If I start to use UEXT for some of my 5V boards (apart of providing 3.3Vcc on connector), all your peripherals are also supporting 5V on their signal lines?
Thanks!

UEXT devices are designed to work at 3.3V so they will not return good levels for your 5V board and I'm not sure if the chips on the modules have 5V tolerant inputs either, this have to be checked for each module individually

Ok, good to know. Thanks for the answer.
So, switching for 3.3V microcontrollers...
