So, i'm working with my robot and i have a problem: the board is deep inside the case, and i have to unscrew it to open and connect the usb cable.
I have an XBee board already inside, so i could use this tutorial to wirelessly program it.
Since this looks like a recurring problem, and since i have many project in mind that use Xbee, i tought: why not having a board with an XBee and an ATMega together? No adapters, no usb, no costly FTDI chips. Sounds cool, uh?
So i went on and installed Eagle to design the board, got scared, disinstalled Eagle and installed Kicad. Much easier. I searched around for the ATMega168 and XBee kicad components, that i found here and there, and started designing the board.
The idea is to have a 3.3V level for the whole board, just to avoid level shifting hassle and such.
The board should be quite easy to make. Stay tuned for some pictures :)
