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.
