GSM/GPRS+GPS/BDS Development board A9G Board \\SMS\Voice\Wireless Data Transmission + Positioning

Development boardIntroduction:

ŸA9GThe development board is based on AnxinkeA9G GPRS/GSM+GPS/BDSMulti-function development board for modules that can be used to verifyA9GThe basic communication functions and peripheral functions of the module.

ŸA9GDevelopment board with basic phone/SMS,GPRSNetworked communication,GPS/BDSDual mode positioning.

ŸA9GThe development board contains lithium battery charge management, microphone, speaker interface,USBCommunication interface, multiple user buttons/led,TFCard slot, acceleration sensor,SPIinterface,I2C2interface,ADCinterface.

ŸA9GDevelopment board camera expansion board, can be connected30W/200Wcamera.

ŸA9GThe development board slot machine expansion board can be connected to a traditional coin machine.

Based on the above functions,A9GCan be used for a variety of peripheral prototyping verification:

ŸuseGPRS+GPS,And an anti-theft device for the acceleration sensor.

ŸuseGSMAnd microphone/Speaker remote monitor intercom

ŸuseGPRS/GSM+GPS,1.54Inch capacitive touch screen smart watch

ŸuseGPRS/GSM+GPSHeart rate blood oxygen sensor,1.54Inch watch with a capacitive touch screen

ŸuseGPRS+TF+Remote surveillance camera for camera expansion board

ŸWeChat payment slot machine solution using the slot machine expansion board

ŸUsing onboard functionality, based onLuaProgrammatic custom device

Basic debugging:

wiring

Development board useATFirmware, used during debugging4Root line connectionUsb-ttl, received debugging on the computer:VUSB→5V;GND→GND;AT_TX→RX;AT_RX→TX;

Or useUSBPower supply, and then connect three more linesGND→GND;AT_TX→RX;AT_RX→TX;

Or powered by a lithium batteryVBAT→(3.3v-4.2)V; GND→GND;AT_TX→RX;AT_RX→TX;(useVBATPower supply, long pressPower_keybutton2sabout)

Power-on

1.A9GThe development board can use a lithium battery orUSBpowered by.

2.Power-on1~2SThe rear module runs automatically, and the serial port will automatically output information at this time. The entire process of powering up to the development board does not require any operation.

3.Need to reset, please pressRst_Keybutton.

4.Module default entryATCommand mode.
