GSM/GPRS+GPS/BDS A9G Development Board Wireless Data Transmission+Positioning

Product overview：
The A9G is a complete quad-band GSM/GPRS module that supports GPRS and GPS/AGPS technologies and is integrated in a compact SMD package, greatly saving customers time and cost in developing GNSS applications. A9G can be widely used in a variety of iot applications, suitable for home automation, industrial wireless control, wearable electronics, wireless location-aware devices, wireless positioning system signals and other iot applications, is the ideal solution for iot applications.

Product characteristics：
1. Complete quad-band GSM/GPRS module, 800/900/1800/1900MHz
2. Sleep current is less than 2mA
3.Support GPS, BDS(Beidou) positioning
4. Support digital audio and analog audio, HR, FR, EFR, AMR speech coding
5. Support voice calls and SMS messages, embedded in the network service protocol stack
6. Support standard GSM07.07, 07.05 AT instruction and Anxin extensible instruction set
7. Support USSD and PBCCH, support UART interface download
8. In terms of software, A9G has both inheritance and innovation:
A9G's AT firmware is fully compatible with the new version of A6 firmware, and those who have A6 and A7 development experience can seamlessly transplant software parts to A9G;
A9G added a smart cloud interface, and can quickly and seamlessly connect to any cloud service provider in the market;
The A9G positioning solution has been connected to the micro public account and Demo App. You can view the device status, location, and historical track online, which is convenient for customers to verify and customize.
A9G adds base station positioning function, using multi-base station positioning algorithm, can accelerate GPS positioning, or in indoor/tunnel positioning without GPS signal;
A9G supports secondary firmware development.
