FlexCore™ Modular Architecture
A three-board FlexCore™ architecture — i-Core compute + i-Function expansion + i-Connect I/O — lets you upgrade compute or I/O without replacing the whole system.
EPC-308O · 7TH GEN INTEL® CORE™
A FlexCore™ modular fanless box PC for multi-serial, dual-network unattended applications
EPC-308O 7th Gen i7 FlexCore Fanless Box PC | 10× COM
The CESIPC EPC-308O is a FlexCore™ modular embedded platform for industrial control, data acquisition and remote equipment. It combines 8× RS232 + 2× RS485, dual Gigabit Ethernet with WOL, rich USB and dual display, 9–36V wide-voltage input and a fanless 6061 aluminum chassis. With TPM 2.0, hardware watchdog and hardware-level auto power-on, it is built for unattended cabinets, transportation and energy sites.
