Description
SIM868 module is a complete Quad-Band GSM/GPRS module which combines GNSS (GPS/GLONASS/BDS) technology for satellite navigation. The compact design with LCC and LGA pads will significantly save both time and costs for customers to develop GNSS enabled applications. Featuring an industry-standard interface and GNSS function, it allows variable assets to be tracked seamlessly at any location and anytime with signal coverage.
