Cost-effective UART GSM Modules USR-GPRS232-7S3 are used for data transparent transmission, which are highly-integrated UART to GSM/GPRS modules. Users can easily make communication with it among serial device, cellphone and network device. It is based on USR-GM3 gprs module. Clients can use the product to realize bidirectional transparent transmission from serial port to network through simple AT command.
