UAV-R21-1 CAN Obstacle Avoidance Radar (1.5–27 m) - IP67 Waterproof
The UAV-R21-1 is a compact, IP67-rated radar sensor designed for UAV obstacle avoidance, providing 1.5–27 m detection range with ±0.1 m accuracy. It interfaces via CAN or UART for seamless integration with Pixhawk, ArduPilot, and other flight control systems.
Features
- Radar-based obstacle detection from 1.5 to 27 meters with ±0.1 m accuracy.
- Dual CAN or UART interface for direct connection to flight controllers (Pixhawk/ArduPilot).
- IP67 waterproof and dustproof housing for reliable operation in harsh environments.
- Compact, lightweight design (105g) minimizes impact on UAV payload and aerodynamics.
- Operates from a wide 5–24V DC supply with low power consumption (<3W).

The UAV-R21-1 Obstacle Avoidance Radar employs a 79 GHz frequency-modulated continuous wave (FMCW) radar system to detect and range obstacles in real-time. Its high-resolution capability (0.12 m) and 20 Hz refresh rate provide the flight controller with timely data for autonomous navigation and collision avoidance maneuvers.
Engineered for aerial robotics, the sensor features a robust IP67-rated enclosure capable of withstanding moisture, dust, and vibration. The wide operating voltage range ensures compatibility with various UAV power systems, from 2S to 6S LiPo configurations, while the selectable CAN/UART interface offers flexible integration into existing communication architectures.
