The GPS/GPRS SIM868 Module is a certified rhomb module that allows GNSS possitionining and GPRS low speed communication. Even more, it has an optional Bluetooth communication interface.
The GNSS part has a low power consumption performance (22~24 mA) and supports various location applications including GPS, GLONASS, BEIDOU, QZSS, SBAS (WAAS, EGNOS, GAGAN, and MSAS) and A-GPS.
The GPRS part, it is quad-band 850/900/1800/1900MHz GSM/GPRS, with maximun speed of 85.6 kbps, available in eSIM and MicroSIM versions.
And about the optional part, it is Bluetooth 3.0 compliant (firmware upgrade required).
All three parts has a 50Ω UMCC antenna conector for each one.
This module has been build around the SIM868 chipset from SIMCOM Technology that integrates GNSS location, GSM/GPRS and Bluetooth 3.0. It can be controlled using the two UART connections or through a high-speed USB interface thanks to the integrated USB controller CP2105. All three parts can be controlled using AT commands in Main UART interface, although it is recommended to use the secondary interface for GPS data because of the amount of frames required.
