DescriptionThe SIM808 GPS/GPRS/GSM Arduino Shield is a compact quad-band GSM/GPRS and GPS navigation technology Arduino shield that is the size of a credit card. This shield is compatible with various mainboards including the Arduino UNO, Arduino Leonardo, Arduino Mega, and others. Compared to the previous generation SIM908, SIM808 has improved performance and stability. Besides the basic SMS and phone functions, the shield also supports advanced features such as MMS, DTMF, FTP, and more. With this shield, you can acquire data, transmit wireless data, develop IoT applications, and use GPS for orientation.What’s it for:Send and receive GPRS data (TCP/IP, HTTP, etc.)Receive GPS data and A-GPS dataSend and receive SMS messagesMake and receive phone callsUsing the SIM808 Arduino shield is quick and easy. With intuitive functions packaged into a single library, you can focus on your project and not waste time studying complex AT commands. 4 Steps to send a GET requestMore ExamplesSPECIFICATIONQuad-band 850/900/1800/1900MHz – 2G GSM networkGPRS multi-slot class12 connectivity: max. 85.6kbps(down-load/up-load)GPRS mobile station class BGPS Receiver channels: 22 tracking / 66 acquisitionCoarse/Acquisition code: GPS L1Tracking sensitivity: -165dBmTime-To-First-Fix: Cold starts: 30s (typ.), Hot starts: 1s (typ.), Warm starts: 28s (typ.)Horizontal position accuracy: < 2.5m CEPUpdate rate: 5HzSupports Real-Time ClockUses standard SIM Card holderOperating voltage: 5VInput Power: 7-23VSupport AT command control (3GPP TS 27.007,27.005 and SIMCOM enhanced AT Commands)Support LED status indicator: Power supply status, network status and operating modesWorking environment: -40 ℃ ~ 85 ℃Size: 69 * 54mm/2.71 * 2.12 inchesWeight: 50gDOCUMENTSWiki (SIM808 GPS/GPRS/GSM Shield For Arduino)SIM808_Shield library on GitHubSIM808 Command Manual SIM808 GNSS Application NoteSIM808 Hardware Design V1.02 SIM808 SPECTEL0097 SchematicSHIPPING LIST1 x SIM808 GPS/GPRS/GSM Shield1 x GPS Antenna1 x GSM Antenna
