NOTE:
1. High and low level of input voltage must locate within the ranges specified in the above table.
2. High and low level of external interface signals must match interface level of this product.
3. VDD_PX=1.8V/3.3V, which indicates the pin voltage, the concrete value please refer to the table 4-1

The following section describes the common pins of module, including the functions of each interface, its default input and output
features, and its matched circuits. The user can reasonably design the application circuits on the system board according to the PIN
descriptions.
The module provides the interfaces/signals as follows:
Power and Reset Interface
UART Interface
USIM Card Interface
USB2.0 interface
Antenna Interface
LED Interface
WAKEUP_OUT & W_DISABLE_N Signal

The host provides power to the module through multiple ground and power pins as summarized in 4.4.1 and 4.4.2. The host must
provide safe and continuous power at all times; the module does not have an independent power supply.

NTERFACE
The GND signal (PIN No: 4/9/15/18/21/26/27/29/34/35/37/40/43/50). This is the power grounding and signal grounding of module.
They need to be all connected to the ground level of system boards. The incomplete connection of GND signals will affect the
performance of the module.

UPPLY
The 3.3Vaux signal (PIN No: 2/24//39/41/52, Power Interface). This is the positive signal of 3.3V/3.8V power, and is also the input
signaling of module’s power. The power supply is recommended to be within the range of
3.0~4.0V(Typ.3.3V/3.8V)
