A9G is a complete quad-band GSM/GPRS+GPS module based on the RDA8955 chip. The cost reduction of the core chip provides users with a cost-effective IoT solution. Integrating protocol stacks such as GSM/GPRS inside, this module supports the basic phone voice call/SMS, serial to GPRS, and GPS data transmission functions, which can be used in a wide range of applications, such as IoT, vehicle-mounted equipment, remote localization, electric power environment monitoring.
Only one mobile phone card or Internet of Things card is needed to enable the device to have information transmission functions such as GPRS/GPS/ SMS/voice call. A9G could also work with other devices by AT command. Besides, the module comes with 29 GPIOs and integrated SDK that could greatly facilitate private redevelopment.
