The USB cable approach is easier to setup and if you just want the usb cable on the left board, you do not need to do anything extra.
### Setting the left hand as master
-If you always plug the usb cable into the left board, nothing extra is needed as this is the default. Comment out `EE_HANDS` and comment out `I2C_MASTER_RIGHT` if for some reason it was set.
