tinyUSBboard on solder-able breadboard
a tinyUSBboard on another solderable breadboard easy to find in Brasil. As the author says: "Arduino compatible without extra programmer and/or FTDI chip (USB<->serial) needed! Plus exchangeable bootloader!"
A ported version to an easy bread board I can find in Brasil. Tested and works ok.
Thanks to Stephan Baerwolf. Nice aproach to an arduino programable without a programmer chip.
Remarks:
- I used an Atmega8 instead of one of the figure.
- there's only 2 breaks on the breadboard: near the usb conection. I used an USB conector sorderable. I have no image to ilustrate, then I used an A-B USB conector on the schema.
I tested everything. It works as programmable board and like a USPasp programmer!
Very nice circuit.

Some recommendations:
- move crystal to a free area to open space for some headers;
- use only neccessary leds;
- maybe, if you place header nearer the atmega, the area could be better used.
