Power
The module requires only +3.3 VDC, 750 mA max. This power must be a well-
regulated +3.3V supply due to limited supply filtering in the module. The digital
inputs and outputs are 3.3V CMOS compatible. See “Power requirements” on
page 36 for specifications.
DISABLE signal The module supports the active low
W_DISABLE# signal (pin 20) as specified in the PCI
Express Mini Card Electromechanical Specification. This signal not only disables the
power supplies to the radio portion of the module, it also powers down additional
portions of the module to reduce power consumption to a minimum.
