Ai-Thinker A9 GSM + GPRS module 

Development

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

BSDK On Chip DevelopmentNo 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
