Introduction
MakePython A9G is an IOT for GPRS / GSM + GPS module, users can use MicroPython to program it, which is very easy, especially for non-programmers. There is also a user guide to learn how to use the board to create the first IOT project, which allows beginners to quickly learn hardware and programming skills.
With this board, you will easy to add text, SMS and data to your project. It is good for your smart home project or GPS tracker and so on.
