Two UART interfaces: one is an ordinary serial port, and one is used for
Bluetooth by default
One I2C interface, supporting only host mode
One SPI interface, supporting only host mode and max. 50 Mbp
One USIM interface, 1.8V/2.85V

Sleep mode is the low power consumption state the module enters. In this mode, peripheral interfaces of the module
are disabled but the RF function works. If a call or SMS message incomes, the module exits from sleep mode. After the
call or voice is end, the module enters sleep mode again.
3
Idle mode indicates the status of no service when the module is running.
4
Current in operating mode indicates the current during data communication. For currents of other network modes
and bands, see N75-NA Current Test Report.

⚫If the voltage is lower than threshold, the module might fail to start. If the voltage is higher than
threshold or there is a voltage burst during the startup, the module might be damaged permanently.
⚫If you use LDO or DC-DC to supply power for the module, ensure that it outputs at least 2 A
current.When the module works at maximum power in GSM mode, the peak current might reach 2A.
Add a large capacitor to the VBAT pin to enhance the capability to output continuous current and
avoid voltage drop.

If the module works in an environment of -35 ℃ to -40 ℃ or 75 ℃ to 85 ℃ , RF performance might be
worse. This does not affect the running of the module. The RF performance will meet the 3GPP standard
after the temperature reaches the operating range.
