A9G GSM/GPRS GPS Module

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
