Application of the STM32MP1 SOM in LoRa Smart Gateway

With the rapid development of digital economy, the industrial Internet of Things (IoT) has achieved leapfrog development in recent years. Smart industrial technologies have been widely applied in the field of intelligent production. By applying sensing, communication, transmission, data processing, and control technologies to all stages of production, including batching and warehousing, the digitalization, intelligence and networking of production and control processes are realized. This enhances manufacturing efficiency, improves product quality, reduces product costs and resource consumption, thereby realizing industrial intelligence.

The industrial Internet of Things (IoT) contains the core elements of intelligence and networking. In the field of manufacturing, logistics and transportation, monitoring and management, connecting offline equipment to the network enables comprehensive data collection, efficient analysis, and real-time feedback. The role of the IoT gateway is particularly important. The IoT smart gateway can integrate and transmit information collected from different things. With the in-depth development of IoT, more and more devices need to be connected, which poses higher demands on the data processing, analyzing ability, transmission capacity and working distance of IoT gateways.
