The Comar COM100-U is a compact, ultra-low-power OEM AIS receiver module with a direct USB interface, designed for manufacturers, electronics developers, integrators and AIS researchers. It provides dual-channel AIS reception in an ultra-light PCB format suited for PC-based navigation platforms, embedded control systems, marine IoT devices, autonomous vessels and portable AIS receivers.

As the successor to earlier USB-only AIS OEM modules—including legacy COM100 USB boards and SLR-series OEM receivers—the COM100-U offers improved receiver sensitivity, cleaner AIS NMEA output and better long-term reliability.

With no Ethernet required, the COM100-U is ideal for simple integrations where a stable USB AIS data stream is the primary requirement.
