I am finally getting my circuit off of the arduino and am using eagle to lay out a pcb.
I have a few questions on how to properly set up the USB to atmel connections.
- I have seen many diagrams and breadboards that do not use any resistors or ferrite beads. They work, but I have feeling I should have some sort of resistors, caps and a bead to help with noise, Fluctuations with voltage, that type of thing.
The circuit works great on a breadboard. I have concerns thou when it gets to a pcb.
What is the proper way of going from the USB header on the board to the atmel? In terms of components And layout?
Any help is greatly appreciated! Thank you
