GSM Modules

GSM module is a GSM RF chip, a baseband processor chips, memory, power amplifier and other devices in an integrated circuit board, which has an independent operating system, GSM RF processing, baseband processing function and provides a standard interface module.

USR IOT GSM module transparent transmission as the core is mainly based on GSM and GPRS network communications, software function perfect, just simple setup, you can achieve two-way serial port to the network transparent transmission. In order to facilitate the user’s choice, our GPRS / GSM module diverse styles, the most simple patch, built-in SIM card style, with a SIM card slot insert needle. Specific functions can click to view specific products.

Currently, GSM module is widely used in the power industry, water industry, the energy industry, the municipal sector, the environmental protection industry, agriculture applications.
