Ai-Thinker GPRS module models are mainly A9, A9G. A9 mainly has GSM/GPRS (2G) related functions; A9G also integrates a GPS chip to facilitate the positioning related applications. For more functions, refer to hardware introduction section.

Module can be bought at taobao or other ways : taobao link

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
• This document does not contains any infomation of AT Command

（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
