Power Module

The Skynode Evaluation Kit includes a power module which is used to power Skynode from a battery with up to 6 Cells (9V to 30V). The power module includes a 5V regulator with a maximum current rating of 5A. Furthermore the power module is used to measure battery voltage and current to the flight controller. Lastly the power module also provides a secondary battery voltage output for the Microhard module. This output is directly connected to the battery input and therefore provides the same voltage level as the input.
