    Lightbulb Building a Custom PSJ-Board with other ATMegas Possible?

    Hello everyone!

    Since the BIG news recently, and the nearly World Wide sold out Teensy and AT90USBkey Boards , im thinking of building my own board!

    I checked my toolbox at home and i think ive got nearly every component I need together, except 2 parts...

    The uC ATMega164.. and i cant define the parts of the released schematic F1 and I1 (possible that these are Zener Diodes or are these Caps ??)

    so besides that, ive got an ATMega8 ( DIP version ) laying around...

    Question is ... Is this possible???

    Anyones help is welcome!!!

    cheers

    Fudd

    I do not think that ATMega8 will suffice, nor will the ATMega164 because the other ic's all have hardware USB, and if you want to put in USB software wise you will need quite a bit of coding.

    Check pages 18,20,21 HERE for help building your own board. I made a few posts on building some, such as tips and information that I know.

    there is a software USB driver for the atmega8, I have used one before for a different project.
    Not sure how much memory etc you would need, and If It would all fit.. but it could be possible

    40€ plus ship is very expensive for a simple microntroller and PCB.

    Supply & demand has really changed things.
