برد SIM808 GPS/GPRS

این برد بر اساس  آخرین ورژن SIM808 ساخته شده است و دارای ویژگی GPS و GPRS می باشد

SIM808 module is a GSM and GPS two-in-one function module. It is based on the latest GSM/GPS module SIM808 from SIMCOM, supports GSM/GPRS Quad-Band network and combines GPS technology for satellite navigation. 

It features ultra-low power consumption in sleep mode and integrated with charging circuit for Li-Ion batteries, that make it get a super long standby time and convenient for projects that use rechargeable Li-Ion battery. It has high GPS receive sensitivity with 22 tracking and 66 acquisition receiver channels. Besides, it also supports A-GPS that available for indoor localization. 

The module is controlled by AT command via UART and supports 3.3V and 5V logical level.
