Power Supply; Power Supply Pins - Quectel EC25-AUX Hardware Design

Hardware:
The W_DISABLE# pin is pulled up by default. Driving it to low level will let the module enter airplane
mode.
Software:
AT+CFUN command provides the choice of the functionality level through setting <fun> into 0, 1 or 4.
 AT+CFUN=0: Minimum functionality mode. Both (U)SIM and RF functions are disabled.
 AT+CFUN=1: Full functionality mode (by default).
 AT+CFUN=4: Airplane mode. RF function is disabled.
NOTES
1. The W_DISABLE# control function is disabled in firmware by default. It can be enabled by
AT+QCFG="airplanecontrol" command, and this command is under development.
2. The execution of AT+CFUN command will not affect GNSS function.
