=== Aux PWR and Aux Batt jumpers ===
As supplied, I do not provide header pins for Aux PWR or Aux Batt pads. If you want to use either of them, solder standard 2.54mm pitch header pin pairs and connect to those.
 
* 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. Any more and you risk damaging the clock chip.
