Introduction of Low Power GPRS Modules
This is a serial uart to GSM / GPRS module
with embedded GPS and LBS Positioning function. It is used for data transparent transmission. USR-GM3P is highly-integrated UART to GSM/GPRS and GPS module. Users can easily make communication with it among serial device, cellphone and network device. USR-GM3P is designed for embedded system, and it is so small and convenient that you can integrate it to your system easily.
