3.4.1.1. Turn on the Module with a Host GPIO

It is recommended to use a host GPIO to control FULL_CARD_POWER_OFF#. A simple reference circuit

is illustrated in the following figure.

Host

Note: The voltage of pin 6 should be no less than 1.19V when it is at HIGH level.

If FULL_CARD_POWER_OFF# is pulled up to VCC with a 5–10 kΩ resistor, the module will be powered

on automatically when the power supply for VCC is applied.

A reference circuit is shown in the following figure.

Notes:

1. The voltage of pin 6 should be no less than 1.19V when it is at HIGH level.

2. The VCC represents the power supply of the module.
