The Comar COM100-NU is the most capable OEM AIS module in Comar’s COM100 family, combining
USB and Ethernet connectivity on a single ultra-compact PCB for maximum
integration flexibility. Designed for OEM manufacturers, maritime electronics companies, universities, defence
projects and research teams, the COM100-NU delivers reliable dual-channel AIS reception in a
low-power, embedded form factor.

As the successor to earlier dual-interface AIS OEM boards – including legacy COM100 modules, USB-only or
Ethernet-only variants and SLR-series embedded AIS receivers – the COM100-NU offers modern throughput, improved RF
sensitivity, stable NMEA output and long-term firmware support. Its small footprint makes it ideal for autonomous
devices, smart AIS sensors, IoT marine units, buoys, solar-powered systems and embedded navigation hardware.

Comar COM100-NU OEM AIS Receiver – Key Features

Replaces / Succeeds

The COM100-NU is intended as the modern replacement for several legacy Comar OEM AIS modules:

• Older COM100 variants that lacked combined USB & Ethernet interfaces
• Systems using COM100-N and COM100-U in combination
• SLR-series OEM AIS modules that required separate USB/Ethernet add-on cards

Key improvements include:

• Dual-output (USB + Ethernet) on a single board
• Higher RF sensitivity and improved DSP performance
• Cleaner NMEA AIS output
• Lower power consumption
• Reduced integration complexity for OEM designs

Typical Applications

• OEM marine electronics and AIS-enabled navigation products
• AIS-enabled IoT devices, gateways and remote monitoring units
• Smart buoys, beacons and aids-to-navigation (AtoN)
• USVs, AUVs and other autonomous surface or subsea platforms
• Raspberry Pi / SBC-based AIS receivers and custom projects
• Marine research, universities and AIS R&D programmes
• Custom commercial AIS sensors and compact enclosures
• Solar-powered and low-energy systems needing AIS input
