3.5. Turn On/Off
3.5.1. Turn On the Module
Driving the FULL_CARD_POWER_OFF# pin to high level will power on the module. The following table
shows the definition of FULL_CARD_POWER_OFF#.
Table 7: Pin Definition of FULL_CARD_POWER_OFF#
3.5.1.1. Turn On through GPIO Controlled FULL_CARD_POWER_OFF#
It is recommended to use a GPIO from the host to control the FULL_CARD_POWER_OFF# pin. A simple
reference circuit is illustrated by the following figure.

3.5.1.2. Turn On Automatically
If FULL_CARD_POWER_OFF# is pulled up to 3.3 V with a resistor of 5–10 kΩ, the module will be
powered on automatically when the power supply for VCC is applied, and be powered off when the power
supply is removed.
A signal to turn on/off the module
When it is at low level, the module
is turned off.
When it is at high level, the module
is turned on.
