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.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.FEATURES32 bit RISC core, frequency up to 312MHz, with 4k instruction cache, 4k data cacheUp to 29 GPIOs (with two download pins)PMU(Power Management Unit): Lithium battery charge management, integrated DC-DC and LDOsQuad-band GSM/GPRS (850/900/1800/1900MHz)Voice callSMSGPS integrated(GK9501), connected with GPRS chip internal through the serial port(UART2), real-time positioningSPECIFICATIONWorking Temperature: ‑20℃ 70℃Low Power Mode Current: 2mA below (average)GPRS Class 10Sensitivity<-105dBGPIO Level: 2.8VSupports GPRS data service, the maximum download data rate is 85.6 Kbps, upload data is 42.8 Kbps.Supports standard GSM07.07,07.05 AT command and Ai-Thinker expandable command setSupports 3 serial Ports, one download serial port, one GPS portAT command supports standard AT & TCP/IP command PortSupports GPS AGPSDOCUMENTSProduct wikiA9G SchematicsA9 SchematicsA9/A9G AT Command SetHardware MaterialA9/A9G Manual-CN
