The power consumption numbers listed in this section are for the
AirPrime SL808X Embedded Module module connected to the host
PC via USB. The module does not have its own power source and
depends on the host device for power. Typical values are measured
at room temperature, and minimum and maximum values are
measured over the entire operating temperature range. For a
description of input voltage requirements, see
page 41.
