Quectel RM510Q-GL - Power On;Off and Reset Procedures

5G Module Series
RM510Q-GL Hardware Design
RM510Q-GL_Hardware_Design 30 / 88
To avoid damages to the internal flash, please cut off power supply after the module is turned off by
pulling down FULL_CARD_POWER_OFF# pin for more than 7 s, and DON'T cut off power supply directly
when the module is working.
3.3.3. Monitor the Power Supply
AT+CBC command can be used to monitor the voltage value of VCC. For more details, see
document [4]
3.4. Turn on
3.4.1. Turn on the Module
FULL_CARD_POWER_OFF# (FCPO#) is used to turn on/off the module. When the input signal is
asserted high ( ≥ 1.19 V), the module will turn on. When the input signal is driven low signal ( ≤ 0.2 V) or
tri-stated, the module will turn off.
This input signal is 3.3 V tolerant and can be driven by either 1.8 V or 3.3 V GPIO. Also, it has internally
pulled down with a 100 kΩ resistor.
Table 8: Definition of FULL_CARD_POWER_OFF#
It is recommended to use a host GPIO to control FULL_CARD_POWER_OFF#. A simple reference circuit
is illustrated in the following figure.
