pin 2 can use the gray wire for 5v instead of 3.3v if your circuit is okay with that

<h2>firmwares:</h2> The arduino environment comes with a few variations of the firmware (<code><path to arduino>/hardware/arduino/bootloaders/atmega</code>)<br> load them like this:<br> <pre> $ avrdude -c buspirate -P /dev/ttyUSB1 -p m328p -U flash:w:ATmegaBOOT_168_atmega328_pro_8MHz.hex </pre> This table shows which arduino (that I own...) uses which firmware<br>
| Filename | Processor | Arduino Boards |
|---|---|---|
| ATmegaBOOT_168_diecimila.hex | ATMega168 @ 16Mhz | Diecimila, Duemilanove, Nano |
| ATmegaBOOT_168_atmega328_pro_8MHz.hex | ATMega328p @ 8Mhz | Pro Mini, Fio |
