To minimize the RF radiation through the power lines, it is suggested to add ceramic capacitors

of 10 pF and 100 nF in the power lines beside the Mini PCIe connector on the host side.

3.5 WAKE# Signal

WAKE# pin (the signal that the module uses to wake up the PC) supports software

control.

This signal is used for module to wake up the host. It is designed as an OC gate, so it

should be pulled up by the host and it is active-low.

When the module wakes up the host, the BB Chip hold 1s high-level-voltage pulse

and then module output low-level-voltage to wake the host.

Figure 3-4 Connections of the WAKE# pin

3.6 RESIN_N Signal

The RESIN_N pin is used to reset the module's system. When the module software

stops responding, the RESIN_N pin can be pulled down to reset the module

hardware.

The RESIN_N signal is internally pulled up to 1.8 V, which is automatically on when

3.3 V is applied and it is active-low.

17

Figure 3-5 Connections of the RESIN_N pin

As the RESIN_N signal are relatively sensitive, it is recommended that you install a 10

nF to 0.1 µF capacitor near the RESIN_N pin of the interface for filtering. In addition,

when you design a circuit on the PCB of the interface board, it is recommended that

the circuit length should not exceed 20 mm and that the circuit should be kept at a

distance of 2.54 mm (100 mil) at least from the PCB edge. Furthermore, you need to

wrap the area adjacent to the signal wire with a ground wire. Otherwise, the module

may be reset due to interference.

The ME909 module supports hardware reset function. If the software of the ME909

module stops responding, you can reset the hardware through the RESIN_N signal as

shown inFigure 3-6 . When a low-level pulse is supplied through the RESIN_N pin, the

hardware will be reset. After the hardware is reset, the software starts powering on the

module and reports relevant information according to the actual settings. For example,

the AT command automatically reports ^SYSSTART.

Figure 3-6 Reset pulse timing



The RESIN_N pin must not be pulled down for more than 1s.



The RESIN_N pin is optional, which can be not connected.



The maximum Forward Voltage Drop of the diode used in the module is 0.6 V.

3.7 W_DISABLE# Signal

The W_DISABLE# signal is provided to allow users to disable wireless

communications of the module.

The software version is planning.

3.8 LED_WWAN# Signal

ME909 provides a LED_WWAN# signal to indicate the RF status.

The ME909 module does not support this function because the software feature is

under development. The planning drive strength is10 mA.

External Circuits

Figure 3-7 shows the recommended circuits of the LED_WWAN# pin. According to

LED feature, you can adjust the LED brightness by adjusting the resistance of resistor

R.

3.9 USB Interface

The ME909 module is compliant with USB 2.0 protocol. The USB interface is powered

directly from the VBAT supply. The USB input/output lines are compatible with the

USB 2.0 signal specifications. Figure 3-8 shows the circuit of the USB interface.
