3.3.1 Overview
The power supply part of the ME906s module contains:
3.3V pin for the power supply
USIM_PWR pin for USIM card power output
Table 3-2 lists the definitions of the pins on the power supply interface.
Table 3-2 Definitions of the pins on the power supply interface
3.3.2 Power Supply 3.3V Interface
The ME906s module power is supplied through the 3.3V pins and the voltage ranges
from 3.135 V to 4.4 V (typical value is 3.3 V). The ME906s provides 5 power pins and
11 GND pins. To ensure that the ME906s module works normally, all the pins must be
connected. The M.2 connector pin is defined as that should support 500 mA/Pin
continuously.
When the ME906s module works at GSM mode, the module transmits at the
maximum power, the transient peak current may reach 2.5 A@3.3 V. In this case, the
power pin voltage will drop. Make sure that the voltage does not drop below 3.135 V
in any case.
The traces of the power supply should be as short and wide as possible. It is
recommended that at least one 220 μF capacitance is added onto the 3.3V power
rails and as close to the M.2 connector as possible. Customers can reduce the
capacitance if it can be guaranteed that the 3.3V pin does not drop below 3.135 V in
any case.
Figure 3-2 shows the recommended power circuit of ME906s module.

3.135 V is the minimum voltage supplied to ME906s by the host, and 3.3V pin must never be
under 3.135 V in any case, which is shown as the following figure.
If the customer wants to power cycle ME906s, the 3.3V pin must stay below 1.8 V for
more than 100 ms. Figure 3-3 shows the power supply timing sequence between
power cycling.

3.3.3 USIM Power Output USIM_PWR
Through the USIM_PWR power supply interface, the ME906s module can supply 1.8
V or 3.0 V power to USIM card. The transient current can reach 200 mA, so special
attention should be taken on PCB design at the host side.
3.4 Signal Control Interface
3.4.1 Overview
The signal control part of the interface in the ME906s module consists of the
following:
Power On/Off (Power_On_Off) pin
Module reset (RESET#) pin
LED control (LED#) pin
WWAN disable control (W_DISABLE#) pin
GPS disable control (GPS_DISABLE#) pin
Wake signal out from module (Wake_On_WWAN#) pin

3.4.2 Power_On_Off Control Pin
The ME906s module can be controlled to be powered on/off by the Power_On_Off
pin.
Table 3-4 Two States of Power_On_Off
If the module is powered by the regulator with 3.3 V
If ME906s is powered by 3.3 V voltage regulator (such as notebook or Ultrabook),
Power_On_Off should be pulled up to 3.3 V through a resistor.
The pull-up resistor should be not greater than 47 kΩ.
Following is the power on/off sequence:
1. The module gets 3.3 V when supply for the module is switched on.
2. The module is turned on since Power_On_Off is pulled up to 3.3 V by the host.
3. Host cuts off 3.3 V supply to power off the module.
The recommended circuit is shown as in Figure 3-4 .
