Product Description
| 2. Introduction This module is 5--26V power, and when the power supply is less than 9V, 2A DC is required. the other power supply port is 3.5--4.2V, which is suitable for lithium battery power. The computer can debug USB--TTL. Suitable for portability. Two sets of antenna SMA ports, GPS and GSM antennas are included. Two sets of IPX ports are convenient to insert into the aluminum box to lead the antenna out. 1 TTL serial port, GPS and GSM functions can be switched arbitrarily. It can realize GPS positioning, SMS, data and other functions, and standby at 80MA{average}. It can provide sleep data, and the power consumption is about 10MA. With voice and microphone interface. It belongs to 4 bands and is available worldwide. 1 GPS antenna interface, SMA interface, can be connected to active antenna (default), can also be connected to passive antenna 1 GSM antenna interface, SMA interface One way voice interface, one way microphone interface One way high-efficiency LDO power supply, the input voltage is 5--26V. Note: When the input voltage is less than 9V, ensure that the power supply can provide 2A. Another power supply port 3.5--4.2V input (suitable for lithium battery power) 1 TTL level interface, compatible with 5V 3.3V 2.85V level system 1 USB interface, which can facilitate the update of SIM808 ancient sword All important pins of the chip are led out. 4. Introduction to use Insert a Unicom or mobile SIM card Insert a GPS antenna, GSM antenna, Bluetooth antenna (just choose to connect the antenna according to your application) When debugging the computer, please connect the USB-TTL module; When controlling the microcontroller, please connect to the serial port of the microcontroller Connect the power adapter Long press (about 2 seconds) to start the button Ready, start debugging 5.
