vice-versa. Replacement arms are prewired with the motor installed and are easily
swappable in the field by removing a single T8 Torx screw.
10.1.6 MULTI-FUNCTION BUTTON
A multi-function button is used during the process of pairing AV to the GCS, among other
functions, including future functionality.
10.1.7 RESET/ FACTORY RESTORE BUTTON
The reset / factory restore button is recessed internally and is accessed through a pin hole
to prevent accidental actuation. A paper clip or other small rigid pin can be used to actuate
it. Pressing and holding this switch for at least 10 seconds before releasing initiates the
following functions:
• Clears all media on either the SD.
• Clears all pairing information, causing a full radio settings re-program on the next
pairing attempt (but does not clear the radio settings that are active on the radio).
• Sends a MAVLink message to PX4 to reset its parameters to default.
• Clears flight logs.
10.1.8 TIME OF FLIGHT SENSOR
An infrared ground-distance sensor on the bottom of the AV works in conjunction with
other on-board (GPS and barometric pressure) sensors to determine the distance to the
ground to assist in landing.
The photo-diode emitter in this ground-distance sensor beams down infrared light, and a
photo-diode receiver senses the reflections from that light to detect the distance to
ground by measuring the “time of flight” of that light. It starts sensing the ground at about
12-15 meters high.
10.1.9 STOCK PAYLOAD
The stock payload on the AV is a dual-axis gimballed FLIR Hadron 640R EO/IR camera
module rated IP54. The payload electrical interface to the AV utilizes plug-in cables for
ease of swapping the payload.
