NOTE:
1. Only two of the five channels on the PCA9518 Device 2 are being used. EN3 and EN4 are connected to GND to disable channels 3 and 4
and/or SDA3/SCL3 and SDA4/SCL4 are pulled up to VCC. SDA0 and SCL0 can be used as a normal I2C port, but if unused then it must be
pulled-up to VCC since there is no enable pin.
