ARM Cortex-A53 / -M4

This IoT gateway is ideal for new Industry 4.0 and retrofit solutions - ready-made for the smart data analysis and controlling use of your machines.

IoT gateways connect sensors and actuators with higher-level systems or convert protocols. Depending on the application, different interfaces and cost-optimized computing power are required. With the phyGATE-Tauri, PHYTEC is already introducing two performance classes of gateways based on top hat rails with uniform expansion options at the start of a series. 

Choose between the high computing power of a 4-core Cortex-A53 system (i.MX 8M Mini) and the low-budget solution based on i.MX 6ULL ​​(1x Cortex-A7 core). Expansion cards are available for both gateways. If you have different performance requirements, you can use our uniform solution and score in your markets with cost-optimized offers. You can create individual interface cards for the expansion bus yourself or you can obtain them quickly and inexpensively from our design service.
