Power Testing

The components for the power management were added and tested successfully.

The reverse protection allows the user to apply charging power to the two screws in the wrong orientation without any damage.


The battery charger IC charges the onboard Li-Po battery when power is applied to the two nuts. The charge current was measured at 45mA which could be reduced very easily by using a smaller configuration resistor.

The voltage regulator was tested and ensures a consistent 3.3 volt is supplied to the circuitry.
