The development board provides a 3.3VDC switching power supply. Either a bench power supply or an AC wall adapter supplies input power to the development board. The required input voltage range is 9–30VDC.

Input power jack, J3

Input power supply

The input power jack, J3, is a barrel connector that accepts 9-30 VDC. The power jack is labeled J3 on the development board. This figure schematically represents the power jack’s polarity:

Ground 9-30VDC +/- 5%

The output current of this regulator is limited to 2.4 amps and the Digi Connect Wi- Wave module draws no more than .750 amps. Using these values as a guideline, and using an 80% efficiency for the switching regulator, the input power supply should be rated to provide at least 3 watts of power.

Important: The development board can use USB power as the power source for the 3.3V regulator. This is accomplished by simply connecting the USB
