This is the A9G GSM/GPRS+GPS/BDS Development Board.
The A9G GSM/GPRS/GPS Development Board is designed around the Ai-Thinker A9G, which features quad-band GSM/GPRS capabilities as well as GPS. The A9G module allows you to easily add SMS, voice, internet connectivity, positioning data and much more to your next project.
The A9G modules allow users to make a voice call, use SMS services, and access the internet and base position with only a SIM or IoT card. These modules operate at -20°C to 70°C temperature range. Applications include IoT, vehicle-mounted equipment, remote localization, and electric power environment monitoring.
