1.8V (3.3V), active low
1.8V, Active Low
Cap close to pin67
When VBAT is always on, must use this design
1.8V tolerence
ME906s is configed as WWAN-SSIC0 internally
CONFIG[3:0] to PC
USB eye debug.
to PC USB2.0 interface
When module on/off is controlled only by VBAT, must use this design
Power_on_off control option 1
RF on: light on
R24 should not be larger than 10K
RF off: light off
1.8V(3.3V),active low

DNI,Reserve for
RC is reserved for RF debug
When use option 1 , R23 must be DNI
USIM absent: CD-->GND;
other devices: for GCF or PTCRB debug.
USIM present: CD Open
C18:to avoid twitter
Tunable antenna SCH
When use option 2 , R24 must be DNI
USB SCH
Config pin SCH
GPIO2 is from SOC
Power_on_off control option 2
GPIO1 is from SOC

When Vgpio2 is ON
Q1 is on and Q2 is off
1.8V (3.3V),open drain ,active low
from proximity sensor
Power_On_Off is controlled by GPIO2
1.8V(3.3V),active low
CONFIG[3:0] is for card type indication and present detection
1.8V(3.3V).high:on,low:off
Power_On_Off is is pulled LOW
DNI: Do Not Install initially.
M.2: new name of NGFF.
Note: If M1 and M2 pin is metal,you can connect it to GND
GND of socket should be well connected to module GND

Q1 is off and Q2 is on
When Vgpio2 is off
Module is shut off safely

USIM_PWR:
#
Module output: 0V or NC

current: 2.5A max
M.2: 3.135V-4.4V,typical 3.3V
One 220uF Tantalum Capacitor is needed to
below 3.135 V in any case.
make sure that the voltage does not drop
USIM_DET Must Be Used.
