KEYESTUDIO SIM5320E 3G Module/GSM GPRS SMS Development Board with GPS Antennas and Adapter for Arduino

Interface Explanation Power Supply: DC 5V 2A or above. Communication Interface: a group of TTL-level serial port, compatible with 5V/3.3V microcontroller; with a USB interface, can be directly connected to the computer debugging. GPS Antenna Interface: a group of IPXmini antenna interface, the default connecting to active GPS antenna. GMS Antenna Interface: a group of IPXmini antenna interface, the default providing PCB antenna. SIM Card Interface: drawer type USB Interface: mini USB interface Voice Mike Interface: Lead out, the interface is a 2.54 * 4P single row pin form. Other Interfaces: a group of IIC interfaces, a group of interface can control the module's opening and closing (the module default self-starting). Indicator LEDs: one LED is used to indicate the working status of the module; another 0603 LED is used to indicate the network status. Preparation 1?Insert the SIM card 2?J2: power supply DC 5V 2A 3?3G ANT interface: connecting 3G antenna 4?GPS ANT interface: connecting GPS antenna 5?Connecting to MICRO USB interface.
