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.

Features

  • Support GSM850/900,DCS1800/1900.
  • Support GSM/GPRS and 2G/3G/4G card, but don’t support 3G/4G network.
  • Support 2 sockets, Support TCP and UDP.
  • 4KB cache for each of sockets, user can choose to cache data or not.
  • Support register packet and heartbeat packet.
