Compulab FACE Module FM-SER – 6× UART Serial Expansion for fitlet® Systems

The Compulab FM-SER FACE Module adds six hardware UART serial ports to compatible fitlet® industrial PCs, enabling reliable connectivity to legacy and industrial equipment in a compact, fully integrated design.

By mounting directly into the system’s FACE slot, the module becomes part of the platform’s cable-free and fanless architecture. This ensures maximum mechanical stability and minimizes points of failure – a crucial factor in industrial automation, transportation, and edge deployments where serial communication is still widely used for control, monitoring, and data acquisition.

With six native UART interfaces, a single fitlet® system can communicate simultaneously with devices such as PLCs, sensors, meters, POS peripherals, access control systems, and industrial controllers. This makes the FM-SER an ideal choice for modern edge solutions that must bridge new software platforms with existing field equipment.

The module is fully supported in both Linux and Windows IoT environments, where native serial interfaces allow for deterministic communication, long lifecycle support, and simplified system integration.
