This SIM808 all in one Shield is a GSM and GPS Bluetooth all-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. The hardware for SIM808 Shield is compatible with the Arduino.

This development board uses the ATmega48 microcontroller for convenient interfacing with the NRF24L01 module. It also features an I2C communication interface that can be used for communication with other microcontrollers such as Arduino or for connecting other peripherals directly to this board. This module comes programmed with an I2C to SPI bridge which implements a convenient RF communication solution. With this module, users do not need to understand the NRF24L01 communication protocol which makes the building of NRF24L01 wireless application easier. This improves the efficiency of the project development process. This module is perfect for robots, remote controls, and remote sensing applications. Specifications Operating Voltage: 5 V (No short-circuit protection) Transfer Rate: 50 Bytes/second I2C/TWI Address: 0x47 (decimal 35) NRF24L01 Address: 0x34, 0x43, 0x10, 0x01, (from low to high)
