$3.6 GPRS GSM MODULE FROM AI THINKER




ShenZhen Ai-thinker CO.,a leading enterprise in the Internet of Things (IoT) industry and the maker of the ESP-12E module, had launched a new killer module: $3.60 GSM GPRS A6 Module!

Providing a chip cheaper than the popular ESP8266 seems to be promising and opens doors for future IoT inventions. This module seems to be a big competitor for SIM900 series module.

This chip is considered the cheapest platform that connects to the internet via GSM/GPRS and at the same time works as a traditional GSM module.

It can be used with AT Commands like the commands for other GPRS/GSM modules SIM800/SIM900. Thus, it is possible to use the same libraries

How To Use A6 GSM GPRS Module:
  1. Connect UART_TXD to RX of the FTDI
  2. Connect UART_RXD to TX of the FTDI
  3. Connect GND to the GND of the FTDI
  4. Connect VCC5.0 To the PWR_KEY pin
  5. Connect a Micro Usb for the power(with any smartphone charger)
  6. After 4-5 second you can remove the connection between VCC5.0 and PWR_Key

You can use it with the Arduino software, just choose a port and open the serial monitor with 115200 baud. To set up the connection send ”AT”, and if you see “OK” then everything works.

A project using the module, download the software, documents, and codes from here. Also watch a test demo.

The module is said to be the smallest available industrial grade quad-band GSM / GPRS module. You can order A6 module for $3.20 from ElectroDragon store.

Datasheet is only available in Chinese. More details about the A6 – A6c – A7 family can be reached at this document and at the A6 module documentation.
