A9G GSM GPS Module
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 A9G module. It has the basic phone/ SMS, GPRS networking communications and GPG/ BDS dual mode positioning function. There are lithium battery charge 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, so you can develop different functions with this board.
A9G development board can be used for various peripherals prototype development verification, such as remote monitoring intercom with GSM and microphone/ speakers, remote monitoring camera with GPRS + TF + camera extension board, wechat payment slot machine scheme with the slot machine function. Besides that, you can also use as automobile theft with GPRS + GPS and accelerometer; 1.54 inch capacitive touch screen smart watch with GPRS/ GSM + GPS; heart rate oxygen sensor and 1.54 inch capacitive touch screen elderly watch with GPRS/ GSM + GPS. Using the onboard features, you can also use custom device based on Lua machine.
