4.5.2. W_DISABLE2#
The module provides a W_DISABLE2# pin to disable or enable the GNSS function. The W_DISABLE2#
pin is pulled up by default. Driving it low will disable the GNSS function. The combination of
W_DISABLE2# pin and AT commands can control the GNSS function.

A simple level shifter based on diodes is used on W_DISABLE1# pin and W_DISABLE2# pin which are
pulled up to a 1.8 V voltage in the module, as shown in the following figure, so the control signals (GPIO)
of the host device could be at 1.8 V or 3.3 V voltage level. W_DISABLE1# and W_DISABLE2# are active
low signals, and a reference circuit is shown as below.
