Smart LTE-M, NB-IoT Gateway for Edge Computing

The SGX31 Smart Gateway builds on the proven EGX81 IoT gateway solution and adds a GPIO connector for applications requiring sensor interfacing, actuator control, data processing or protocol translation at the edge.
Offering out-of-the-box worldwide Cat-M or NB-IoT connectivity with 2G fallback, the SGX31 Smart IoT Gateway provides a flexible, cost-effective platform for connecting industrial assets using the latest LPWA technology. The smart gateway adds support for USB, a dedicated GNSS antenna and embedded processing via the Telit Cinterion ThreadX SDK.

Telit Cinterion SGX31 IoT Gateway

Product Description

The SGX31 offers affordable LTE connectivity with data speeds of up to 300 kbps for applications that require cost-effective, efficient data speeds.

The 20-pin GPIO connector (GPIOs, SPI, I2C, PWM) enables a wider range of applications, making the SGX31 ideal for industrial monitoring, industrial sensors, asset tracking, security and agricultural applications. The gateway connects sensors, IoT modules and smart devices to the cloud, giving devices access to the Internet with edge computing.

Form Factor Family
