Digital AirSpeed Sensor – ASPD-AUAV (Matek)

Meet the ASPD-AUAV — a high-precision, fully digital airspeed sensor built for UAVs and fixed-wing aircraft. It’s built around the AUAV-L30D sensor, supports DroneCAN and I²C, and is compact and low weight so you won’t regret mounting it. (We sell it, yes.)

Why You Want It

Because analog pitot sensors are old news. With its CAN / I²C interface, native support for ArduPilot as a periph node, and wide speed range (up to 400 km/h), this sensor gives you reliable measured airspeed data for flight controllers without analog noise, drift, or wiring hassle. Swap it between builds without re-engineering your plumbing.

Specifications

• Sensor element: AUAV-L30D differential pressure sensor (All Sensors DLVR class) 
• Interfaces: CAN (DroneCAN protocol), I²C, UART (MSP)

• Operating temp: –30 °C to +85 °C 
• Dimensions: 36 × 32 × 7.3 mm
• Weight: ~ 5 g

What’s in the Box*

• 1 × ASPD-AUAV sensor board
• 1 × Pitot tube

Still Here?

If you’re running fixed-wing, VTOL, or hybrid rigs using ArduPilot or DroneCAN, this sensor slashes your setup pain. Plug it into a CAN bus or I²C line, set the ARSPD_TYPE/USE parameters, and let the flight controller do the rest. Want a UK stock, bulk discount, or alternate mounting option? Just holler.
