5 V instead of 3,3V
Dear nice guys,
is it possible to have on every analog and digital output 5 V instead of 3,3 V. Or is there maybe a "shield" (with potential-free switches) I can use to toggle my 5V (external) DC Supply?
I just started trying things with my new L152RE an some additional components.
If anyone knows anything, I would be glad to hear from you .
nice times
H.B.

No. Digital inputs are often (but not always) 5V tolerant, but outputs and analog inputs are for every mbed target 3.3V. There surely is a shield that has a relais which can toggle 5V.
