V2- Hand made
I wanted to bring down the cost of the parts for the controller so I checked into using different parts to bring down the cost. I also removed the EEPROM from the board because I ran out of room because I used a larger buzzer. Also I was not happy with the connectors used and was having trouble finding surface mount components with a .1in spacing so I switched to a 2mm spacing. The connectors are very nice.

These next two pictures are of the revised board known as V2.
The most
obvious difference is the different style connectors.
