Digital AirSpeed sensor ASPD-DLVR
Digital AirSpeed Sensor ASPD-DLVR – Precision AirSpeed Measurement for UAVs
Currently the best supported speed sensors by ArduPilot.
Key Features of the Digital AirSpeed Sensor ASPD-DLVR
- CAN node ArduPilot AP_Periph F303,
- DLVR-L10D firmy All Sensors, industrial temperature range,
- CAN and I2C interface,
- Typical platforms: Fixed-Wing, QuadPlane, VTOL,
- CAN JST-GH connector, UAVCAN protocol,
- I2C connector JST-GH, DLVR-L10D I2C mode (I2C address 0x28),
- UART1, software update,
- UART2, spare for external GPS,
- UART3, MSP protocol (to be supported),
- 3.3 V power LED, red,
- CAN bootloader LED (blue)
- Fast blinking: No communication between the CAN node and flight controllers (bootloader AP_Periph mode),
- Slow blinking: Successful communication established between the CAN node and flight controllers.
