4.5.3. WWAN_LED#
The WWAN_LED# signal is used to indicate RF status of the module, and its sink current is up to 10 mA.
To reduce current consumption of the LED, a current-limited resistor must be placed in series with the
LED, as illustrated in the figure below. The LED is ON when the WWAN_LED# signal is at low level.
