V2.0 design finished.
Basically a polished up version of the v1.0 board
Mostly only minor fixes. These include:
- Labels on the Arduino Mega pins.
- Labels on the board pins.
- Power header added.
- I2C address selector on IO expander fixed.
- Board size adjusted
At this point, the V2.0 board has not been tested.
Files will be available for those who wish to make it
