Just one question before I try building it: Isn't USB data voltage specified to be TTL (3,3V) and doesn't the pic put out 5V? Shouldn't therefore be a limiter (like a zener diode) on the data lines like for example on an USBasp?

Hi.
Thank's for the great project.
Just one question before I try building it: Isn't USB data voltage specified to be TTL (3,3V) and doesn't the pic put out 5V? Shouldn't therefore be a limiter (like a zener diode) on the data lines like for example on an USBasp?
All USB PIC devices have an on-board 3.3V regulator so everything is in spec.
Thank you for the answer. :)
