CAUTION! The module’s +3.3V (pin 15 for Digi Connect ME 9210 Family and pin 9 for Digi
Connect Wi-ME 9210 Family) has the equivalent of a 500uF capacitor connected between
it and GND. At power on, this equivalent capacitance will cause an input inrush current
that is dependent on the voltage rise time of the user supplied +3.3V power source. This
user supplied +3.3V power source must be able to supply the needed inrush current
