Ai-Thinker A9G GSM + GPRS + GPS module 


The development of modules mainly provides two kinds of interfaces:

(A) AT Command: a module connect with MCU with UART

  • It's a easy way to operate GSM/GPRS module, and requires MCU to send command to the module through a serial port(UART), and you just need to find the command you need in AT Command Documentation
  • AT firmware is the default firmware, you can set up immediately, more refer to Ai-Thinker Wiki

(B)SDK On Chip Development,No external MCU is needed, burn the firmware directly to GPRS module

  • The advantage of this method is that it doesn't need extra MCU, programming directly on modules, saving hardware resources, and save mony for projects

  • This documentation introduces in detail how to use SDK to develop and provide related API docs.

  • The AT application source code is not included in this SDK

  • 1 A9G module (the board be the same that with A9 and A9G, for the A9 and A9G in the same package, the same pin )
  • 29 GPIOs with 2.45mm spacing (with 2 download debug pins (HST_TX,HST_RX)
  • One SIM card slot (Nano Card <Micro Card <Standard Card)
  • 1 TF card slot
  • 1 GPRS interface with IPEX 1 generation package
  • 1 GPS interface with IPEX 1 generation package
  • 1 micro USB interface
  • 5v-4.2V DC-DC, it can be 5v power supply or 3.8 ~ 4.2V power supply
  • 1 accelerometer chip(LIS3DHx)
  • 1 power key, and a reset button
  • 2 LED
  • 1 microphone
