Description GPRS/GSM + GPS A9G Pudding/SMS/Voice/Wireless Data Transmission + Positioning IoT Development Board
The A9G development board is a multifunctional development board based on EMC's A9G GPRS / GSM + GPS / BDS module.
You can use it to verify the basic communication and peripheral functions of the A9G module.
It has the basic telephone / SMS, GPRS network communication and GPG / BDS dual mode positioning function.
There are lithium battery management, microphone, speaker interface, USB communication interface, multiple user keys / LED, TF card slot, acceleration sensor, SPI interface, I2C2 interface, ADC interface on the boards.
This is so that you can develop different features with it board.
The board has a camera expansion card, so you can connect an external 30W/200W camera.
It is also possible to use a slot machine function.
The A9G development board can be used for various peripheral prototype development verification, such as remote monitoring intercom with GSM and microphone / speakers, remote surveillance camera with GPRS + TF + camera expansion card, wechat payment machine schedule with the slot machine function.
You can also use it as:
- car theft with GPRS + GPS and accelerometer
- 1,54 inch capacitive touch screen smart watch with GPRS / GSM + GPS
- heart rate oxygen sensor
- 1,54 inch capacitive touchscreen elderly watch with GPRS / GSM + GPS.
Using the built-in functions, you can also use a custom device based on the Lua machine.
