The MatekSys ASPD-DLVR is a high-precision digital airspeed sensor designed for advanced fixed-wing, QuadPlane, and VTOL UAV platforms. Featuring support for both CAN/DroneCAN and I²C communication interfaces, this compact sensor delivers accurate airspeed readings and seamless integration with popular flight controllers such as ArduPilot and PX4-based systems. 

Constructed around the industrial-grade DLVR-L10D differential pressure sensor, the ASPD-DLVR offers a robust operational range and reliable performance in varied flight conditions, making it ideal for precision flight control and aerodynamic adjustments. 

Key Features:

• Digital airspeed measurement via CAN/DroneCAN or I²C interface for modern UAV integration. 

• Compatible with ArduPilot AP_Periph or direct I²C mode (address 0x28) for flexible flight controller setup. 

• Built-in LEDs indicate CAN bootloader and power status. 

• Industrial-range operating temperature for reliable performance. 

• Compact, lightweight design (≈4 g) with supplied pitot tube and tubing for installation. 

Specifications:

• Input voltage range: 4.5 V – 5.5 V. 

• Power consumption: ~60 mA. 

• Pressure range: ±2500 Pa (±10 inH2O) with robust burst tolerance. 

• Speed measurement range up to ~227 km/h. 

• Small form factor (~22 × 22 × 12.5 mm) and light weight (~4 g).
