TBS Lucid DroneCAN Airspeed Sensor
by Team Black Sheep

The TBS Lucid DroneCAN Airspeed Sensor is a high-performance digital airspeed solution designed specifically for fixed-wing and VTOL aircraft. Unlike traditional analog sensors that can suffer from signal drift and electrical noise, this module provides a clean, noise-free digital signal via the DroneCAN protocol. It is a vital component for professional pilots who require accurate air data to optimize autopilot performance, improve stall prevention, and manage energy consumption during long-range or technical missions.

Equipped with the industry-standard MS4525DO pressure sensor, the Lucid provides a broad measurement range suitable for most fixed-wing applications. It features a versatile dual-interface design, allowing for a primary digital connection via the JST-GH CAN port or a secondary direct I2C connection. With a measurable airspeed range of up to 360 km/h (223 mph) and integrated status LEDs for real-time communication feedback, this sensor offers a reliable, plug-and-play experience for both ArduPilot and PX4 users.

Key Features

• Dual Interface Connectivity: Supports both CAN (DroneCAN) and I2C (MS4525DO) protocols via standard JST-GH connectors.

• Wide Velocity Range: Accurately measures airspeeds up to 360 km/h (100 m/s), covering everything from slow gliders to high-speed sport planes.

• DroneCAN Precision: Digital output eliminates the signal sag and interference common with traditional analog airspeed setups.

• Real-Time Status LEDs: Includes a 3.3V power LED and an orange CAN status LED for instant diagnostic feedback.

• Ultra-Lightweight Design: Weighs only 4g, ensuring negligible impact on the airframe's center of gravity.

• Complete Installation Kit: Comes with a stainless steel pitot tube and silicone tubing for immediate mounting.
