GPRS Module USR-GPRS232-7S3 Introduction of Cost-effective UART GSM Modules
GPRS Module USR-GPRS232-7S33 are Cost-effective UART GSM Modules 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. USR-GPRS232-7S3 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.
