Compulab FACE Module FM-4USB – 4× USB Expansion for fitlet® Systems

The Compulab FM-4USB FACE Module is a compact expansion module that adds four additional USB ports to compatible fitlet® industrial PCs. It is designed for edge and IoT deployments where multiple peripherals must be connected reliably without using external hubs.

Built for seamless mechanical and electrical integration, the module mounts directly into the FACE slot of the system, maintaining the platform’s rugged, cable-free design. This ensures high stability, reduced failure points, and a clean installation – essential in industrial, digital signage, and embedded environments.

With the FM-4USB, a single system can handle multiple USB devices such as cameras, storage media, license dongles, input devices, or IoT gateways. This makes it ideal for solutions that require centralized device management and long lifecycle hardware.

From a platform perspective, the module fits naturally into Linux-based and Windows IoT deployments, where reliable USB connectivity is critical for sensors, automation equipment, and edge data collection.
