FrSky Smart Port Air Speed Sensor ASS-70/ASS-100 is a speed sensor for aircraft. It can provide flight speed data for the entire flight.
This manual provides instructions for the FrSky ASS-70 and ASS-100 Air Speed Sensors, designed for use with FrSky Smart Port enabled systems. The document details the specific operational voltage, current consumption, and measurement ranges for both models, noting that the ASS-70 measures up to 270km/h while the ASS-100 measures up to 360km/h.
The guide covers the physical assembly of the pitot tube and circuit board, recommended installation positions to ensure accurate readings by avoiding prop-wash, and connection procedures to the receiver's Smart Port. It also explains how to identify sensor status via LED flashing patterns and mentions the ability to change the default physical ID using a FrSky Servo Channel Changer.
| Operational Voltage | DC 4-10 V |
|---|---|
| Current consumption (ASS-70) | 20mA@5V |
| Current consumption (ASS-100) | 25mA@5V |
| Measure airspeed range (ASS-70) | 0~270km/h |
| Measure airspeed range (ASS-100) | 0~360km/h |
| Default physical ID | 10 |
The default physical ID for this sensor is 10.
Yes, the ID number could be changed by FrSky Servo Channel Changer.
A quick LED flash indicates that the Smart Port connection is YES and Airspeed is provided YES.
