INTERFACE FUNCTIONS

• GPS Antenna: this is an uFL GPS antenna connector. You can connect either passive or active GPS antenna to it. Active GPS antenna runs at 2.8V voltage.
• MicroUSB: the charging interface for Li-Ion battery, of input voltage range from 5V to 7V. Beside, it is also the software debugging interface for SIM808 that you can upgrade firmware and debug software.
• Power Button: this is the hard power switch for the module. When the module is power up, you can turn on or turn off the module by pressing the button for 2s.
• Net Indicator: Red LED, it will tell the what status is about the module linking to network.
• Status Indicator: Green LED, it will tell whether the module is on, light when the module is running.
• Li-ion Battery: this is power supply for the module, input voltage is from 3.4V to 4.4V. It uses the XH-2.0mm connector, that make it convenient to connect to 3.7V Li-Po Battery.
• GSM Antenna: this is an uFL GSM antenna connector, just connect it to a GSM antenna for receiving GSM signal.
• SIM – Card Holder: SIM card holder for standard SIM card
• Microphone: this is the reserved interface for 2.8V microphone. By using the microphone, you can make voice calls and collect speech data around the module.
• VRTC: RTC backup. You can add external capacitor or rechargeable battery on it.
