/* Aux PWR and Aux Batt connectors */
* Aux PWR is a 5v power line that is fed from the host computer. It is supplied as a convenience to allow you to provide power to other devices. Do not attempt to use it as a power input.
* Aux Batt is an alternative battery connector, to be used if you do not want to use the built in CR2032 button cell. If you use Aux Batt, you *must* remove the button cell first, and the voltage you need to apply is ~3v- 5v. Any more and you risk damaging the clock chip.
For both connectors, observe the connection polarity printed on the PCB.
