DESIGN PHILOSOPHY

Three Boards Separated · Bus-Coordinated · Freely Combined

FlexCore™ splits the traditional single-PCB industrial mainboard into three layers — compute / control / connectivity. i-Core carries the CPU, i-Function handles functional differences, and i-Connect integrates field I/O. Any layer can be upgraded independently, while the platform can be frozen for 5–7 years.

5 SCHEMES · 18 VARIANTS

5 system schemes · 18 interface variants

Every scheme shares the i-Core compute board platform ── simply by swapping the i-Function expansion board and i-Connect I/O board, you can derive system interface configurations tailored to different industrial scenarios.

A
Standard I/O · best value

Scheme A · Economy Base Interfaces

An economical combination for general industrial control ── a single LAN port plus standard USB / display / audio / power, with COM serial ports expandable as needed (0 / 3 / 5). It is the go-to configuration for entry-level ComputeOps™ industrial PCs.
