SIM808 GSM/GPRS/GPS IoT Board (Arduino Leonardo Compatible)
IntroductionThis is an SIM808 GSM/GPRS/GPS IoT Board based on Arduino Leonardo. The SIM808 with Leonardo mainboard is the latest development board for multi-purpose applications. The onboard SIM808 module includes an integrated quad-band GSM/GPRS and GPS satellite navigation module, and a 4 layer PCB integrates the microcontroller, microphone, headphone jack and GPRS/GPS, giving this board the tiny footprint of a regular credit card! Meanwhile, the board includes a sleep mode feature for extra-low power consumption. And an on-board 3.7V Lipo battery power supply and battery-charging circuit has been integrated into the board, making it ideal for applications such as real-time car tracking, security patrolling, and IoT projects.Compared with the existing SIM808 modules on the market, this SIM808 uses the latest version with better stability. And it has Bluetooth now.how to track and locate objects or people with the sim808 using GPS and SMS and google mapsApplicationsGPRS network nodesRemote communicationsSatellite positioningReal-time car tracking systemsSecurityInternet of things (IoT)SpecificationAVR Arduino MCU: ATmega32u4 (Bootloader: Leonardo) Operating voltage: 5VInput Voltage: 5V (USB)/7~23V(Vin)/3.5~4.3V (BAT)Low-power consumption: (100mA@7V-GSM mode)Digital I/O Pins: 20PWM Channels: 7Analog Input Pins: 12DC Current per I/O Pin: 40 mADC Current for 3.3V Pin: 50 mAFlash Memory: 32 KB (of which 4 KB is used by the bootloader)SRAM: 2.5 KBEEPROM: 1 KBClock Speed: 16 MHzWireless Module: SIM808 GSM/GPRS/GPS module Quad-band 850/900/1800/1900MHz ¨C 2G GSM networkGPRS multi-slot class 12/10GPRS mobile station class BCompliant to GSM phase 2/2+Class 4 (2 W @ 850/900MHz)Class 1 (1 W @ 1800/1900MHz)Bluetooth: Compliant with 3.0 + EDRTime-To-First-FixCold starts: 30s (typ.)Hot starts: 1s (typ.)Warm starts: 28s (typ.)Accuracy: Horizontal position 2.5m CEPUpdate rate: 5HzControl: AT command (GSM07.07, 07.05 and SIMCom enhanced AT commands)Dimension: 73*54mm / 2.87* inchesWeight: 50gShipping ListSIM808 with Leonardo mainboard x1Built-in Spring GSM Antenna x1Built-in GPS antenna x1
