A9 chip is a complete quad-band GSM / GPRS module, 800/900 / 1800 / 1900MHze. Its stable performance, the appearance of compact, cost-effective, could meet the diverse needs of customers.
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.
Users could upload the information of module position to WeChat Mini-Programs or other APPs with only a SIM or IoT card, and then directly check the position information on the phones. 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.
