توضیحات

A9G GSM/GPS MODULE:

A9G GSM/GPRS+GPS breakout board based on the Ai-think A9G module, which is the newest GSM GRPS+GPS Quad-Band module. The A9G can be used in a wide range of IoT applications and is ideal for IoT applications for home automation, industrial wireless control, wearable electronics, wireless location sensing devices, wireless location system signals, and other IoT applications. The Minimum System is controlled via AT commands, and fully compatible with Arduino/Maduino.

Possible application:

Vehicle immobilizer using GPRS + GPS, as well as accelerometer.
Remote monitoring intercom using GSM and microphone / speakers
Smart watch with 1.54 “capacitive touch screen using GPRS / GSM + GPS
Use GPRS / GSM + GPS, heart rate sensor, 1.54-inch capacitive touch screen monitor the elderly care
Remote monitoring camera using GPRS + TF + camera extension board
Wechat payment slotting scheme using slot extension board
Custom devices based on Lua programming using onboard functions

Package of development board

Main development board, accelerator IC is not placed on board.
GPS/GPRS antenna, and GPS/BGS antenna.

Quick Start Guide
Basic debugging: wiring

Development board using the AT firmware, when used in debugging 4-wire connection usb-ttl, connected to the computer debugging: VUSB → 5V; GND → GND; AT_TX → RX; AT_RX → TX;
Or use the USB power supply, and then another three lines GND → GND; AT_TX → RX; AT_RX → TX;
Or lithium battery VBAT → (3.3v-4.2) V; GND → GND; AT_TX → RX; AT_RX → TX; (VBAT power supply, need to press power_key button for about 2s)

Power-on

A9G development board can use lithium battery or USB power supply.
Power 1 ~ 2S module automatically run, this time the serial port will automatically output information. The entire power to the development board to work properly does not require any operation.
To reset, press the Rst_Key button.
The module enters AT command mode by default.

Initilization

Under normal circumstances, the module power-on initialization is completed flag is + CIEV: READY, the actual module at initialization time requested data from the base station, will issue the date, time zone and time zone information, due to network reasons, will READY After the output. Of course, after the READY appears, it means the module power-on initialization is completed.

Auto-Tune Baudrate

A9G has a baud rate adaptive function, the default baud rate is 115200. In the module initial power-on, you can modify the module’s baud rate. For example, my MCU baud rate is 9600, then the module just power up, send a command AT (not limited to this command, only to adjust the baud rate), the module will automatically adjust the wave Special rate to 9600.
