Resistor Settings
VDD_SERVO_1 and VDD_SERVO_2 can be connected together by shorting the pads of the large unpopulated resistor. Either with solder or a 0 Ohm 0805 resistor.
The I2C address can be changed by moving the resistors from the left position to the right position to change the bit from 0 to 1.
