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 6UL (1x Cortex-A7 core). Expansion cards are available for both gateways. If you have different performance requirements, you can rely on our standardized solution and score points with cost-optimized offers in your markets. You can create individual interface cards for the expansion bus yourself or obtain them quickly and inexpensively from our design service.


Your benefits:

  • Price / performance optimization through two selectable systems:
    i.MX 6UL or i.MX 8M Mini
  • Individual expansion for your interface requirements through standardized backplane bus
  • Space-saving solution through on-board expansion
  • Individual interface expansions at low cost
  • Simple integration of your systems in cloud solutions through existing example implementations
  • Offer your customers security through Secure Boot, Secure Root File System and certificate management
  • Long-term solution right from the start with current Linux / Yocto versions with long-term maintenance
  • Offer your customers an update service through device management solutions from PHYTEC
  • Future-proof through long-term maintenance and expansion
