Based on the AUAV-L30D differential pressure sensor , it offers improved still-air offset performance and a wider measurement range compared with many traditional airspeed sensors.\u003c\/p\u003e\n\u003cp\u003eThe sensor supports UAVCAN (DroneCAN), I²C, and MSP interfaces , allowing flexible integration with modern flight controllers and autopilot systems. UAVCAN connectivity provides robust digital communication and simplified wiring for aircraft using CAN-based avionics networks.\u003c\/p\u003e\n\u003cp\u003eWith a maximum airspeed measurement of up to 400 km\/h , the ASPD-AUAV is well suited for fast fixed-wing platforms, VTOL aircraft, and long-range UAVs. Despite its capability, the sensor remains lightweight and efficient, drawing only around 26 mA and weighing approximately 5 g .\u003c\/p\u003e\n\u003cp\u003eCompact and easy to integrate, the ASPD-AUAV provides precise airflow data that can improve flight efficiency, autopilot performance, and stall protection.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDual interface support (DroneCAN\/CAN + I2C) for flexible wiring and system compatibility\u003c\/li\u003e\n\u003cli\u003eBased on the AUAV-L30D differential pressure sensor for high precision and minimal drift\u003c\/li\u003e\n\u003cli\u003eWide speed measurement range up to 400km\/h (≈111 m\/s) covering fast fixed-wing and UAV builds\u003c\/li\u003e\n\u003cli\u003eLow power consumption (~26mA) and compact form factor (36×32×7.3mm) make it suited to light aircraft\u003c\/li\u003e\n\u003cli\u003eCompatible with ArduPilot as AP_Periph peripheral node for telemetry and flight-data logging\u003c\/li\u003e\n\u003cli\u003eInput voltage range of 4.5V–5.5V simplifies power supply integration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eInterfaces:\u003c\/p\u003e\n\u003cp\u003eCAN JST-GH connector, DroneCAN Protocol\u003c\/p\u003e\n\u003cp\u003eI2C JST-GH connector, AUAV-L30D I2C mode\u003c\/p\u003e\n\u003cp\u003eTX2, MSP protocol\u003c\/p\u003e\n\u003cp\u003eWiring and AP Parameters\u003c\/p\u003e\n\u003cp\u003eAP_Periph \u0026amp; DroneCAN protocol\u003c\/p\u003e\n\u003cp\u003eFirmware https:\/\/firmware.ardupilot.org\/AP_Periph\/latest\/MatekL431-AUAV\/\u003c\/p\u003e\n\u003cp\u003eAP_Periph https:\/\/github.com\/ArduPilot\/ardupilot\/blob\/master\/Tools\/AP_Periph\/README.md\u003c\/p\u003e\n\u003cp\u003eDroneCAN protocol https:\/\/dronecan.github.io\/\u003c\/p\u003e\n\u003cp\u003eTips\u003c\/p\u003e\n\u003cp\u003eCAN Baro is enabled by default, If you don’t use the Baro integrated in AUAV, set “BARO_ENABLE = 0” in “Mission Planner-\u0026gt;Initial Setup-\u0026gt;Optional Hardware-\u0026gt;UAVCAN-\u0026gt;MAVlink CANx -\u0026gt; Menu Parameters”\u003c\/p\u003e\n\u003cp\u003eArduPilot has removed AUAV I2C support by default on flight controller with 1MB flash MCU(such as F405, F745 series).\u003c\/p\u003e\n\u003cp\u003eAUAV vs. DLVR\u003c\/p\u003e\n\u003cp\u003eExample log comparison of the AUAV-L30D and DLVR sensors, showing the AUAV providing a cleaner zero-airspeed baseline and wider measurable speed range.\u003c\/p\u003e\n\u003cp\u003eSpeed range 400km\/h vs 227km\/h\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eModel: Matek Digital Airspeed Sensor ASPD-AUAV\u003c\/li\u003e\n\u003cli\u003eInput voltage: 4.5V–5.5V\u003c\/li\u003e\n\u003cli\u003ePower consumption: ~26mA\u003c\/li\u003e\n\u003cli\u003eSpeed range: 400 km\/h (≈111 m\/s)\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: -30°C to +85°C\u003c\/li\u003e\n\u003cli\u003eDimensions: 36×32×7.3mm\u003c\/li\u003e\n\u003cli\u003eWeight: ~5g\u003c\/li\u003e\n\u003cli\u003eInterfaces: DroneCAN (JST-GH), I²C, UART (MSP)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIn the box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x ASPD-AUAV Sensor\u003c\/li\u003e\n\u003cli\u003e1x Pitot tube\u003c\/li\u003e\n\u003cli\u003e2x 20cm connecting cable\u003c\/li\u003e\n\u003cli\u003e1x 40cm silicone tubing\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Matek Systems","offers":[{"title":"Default Title","offer_id":58941160849740,"sku":"FC-M-ASPD-AUAV","price":97.9,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1087\/9952\/5196\/files\/Matek-Digital-AirSpeed-Sensor-ASPD-AUAV.jpg?v=1790286355","url":"https:\/\/dronepart.co.uk\/products\/matek-digital-airspeed-sensor-aspd-auav-uavcan","provider":"My Store","version":"1.0","type":"link"}
