NanoRadar UAM231 24GHz Altimeter Radar - 1000m Range, IP67, UART/CAN/RS232/422/485

The UAM231 uses 24GHz FMCW radar to provide terrain-aware altitude measurements, meaning it outputs elevation data that reflects actual ground undulations. Unlike GPS, which gives geometric altitude without terrain detail, or barometers, which are affected by weather, the UAM231 delivers stable, accurate ground-referenced height even in rain, fog, or over complex landscapes.

The module supports UART (TTL-level), CAN, RS232, RS422, and RS485 interfaces. The active interface is typically configured via software commands sent over the UART port during initialization. You must connect to the corresponding physical pins on the connector and ensure your host system's communication protocol (e.g., Modbus for RS485) matches the sensor's configured output mode.

The UAM231 requires a 24V DC power supply as per its specifications. Operating outside this rated voltage, such as with 5V or 12V inputs, is not recommended as it may lead to insufficient performance, sensor damage, or complete failure. Always use a stable 24V source that can deliver the required current for the module's 1.8W power consumption.

Yes, the UAM231 is specifically designed for high-vibration UAV applications. It features a ruggedized construction, IP67 environmental sealing, and internal algorithms that filter out vibration-induced noise. Its performance has been validated over numerous test flights, making it ideal for integration into multi-rotor drones, fixed-wing UAVs, and other dynamic aerial platforms.

The onboard 6-axis IMU (gyroscope, accelerometer, magnetometer) allows for sensor fusion, improving altitude data stability during aggressive maneuvers and providing attitude angle warnings to ensure the module is installed within its optimal orientation. The self-check system continuously monitors hardware and software health, enhancing data reliability and operational safety by alerting the host system to potential faults.
