Electronic module Sim808 Development Board Replaces Sim928 Module GSM GPRS GPS BT

•Quad-Frequency 850/900/1800/1900MHz

•SMS

•FTP/HTTP, Embedded TCP/UDP Protocol

•DTMF Detection, Bluetooth 3.0 (Optional),USB Interface

•The Power Interface Supports 5V Voltage Input. Note That When the Voltage Is 5V, the Power Adapter Current Can Provide No Less than 2A; Support Lithium Battery (3.6-4.2V)

•The Communication Interface Is TTL Level Serial Port. It Is Fully Compatible with Arduino and Other 5V,3.3V and 2.85V Systems.

•You Can Choose to Use Hardware Serial Port (D0 D1) Or Software Serial Port (D7 D8) through Jumper Cap.

•SupportMICRO SIMCARD.

•Supports Four-Segment Headset Interface (Type I).

•Supports Updating Sim800c Firmware through USB Or Serial Port.

•Can Be Upgraded to a Development Board with Bluetooth Version.

•on-Board Transient Voltage Suppressor, Sim Card Protection Ic, Two 100Uf Tantalum Capacitors and Other Methods Make the Development Board Stable Performance.

•Communicate with External Systems through TTL Level Serial Ports. by Default, It Can Directly Communicate with 5V Systems without Level Matching. When Communicating with 3.3V System and 2.85V System, Some Hardware Processing Is Required. We Will Introduce It in Detail in the User Manual.

•The Communication Interface (Command) Is at Instruction, That Is, the Function of the Control Module Is Completely Realized through at Instruction, for Example, the Control Module Calls the Phone Using ATD * * * * * * *;(* for the Phone Number of the Other Party). We Will Provide a Complete at Instruction Set.
