For temperature and ingress protection info, please refer to the technical specs section:
No hotswap protection. Do not mate or demate Smart Dovetail while the aircraft is powered.
If the payload has even modest capacitance or other inrush current the connector contacts on both aircraft and payload side will be eroded.
We have tested this payload up to a speed of 15m/s, climb rate of 4m/s, and descent rate of 3m/s. There has been no significant performance testing past these limits. Refer to the performance section of the Astro wiki for more information.
Wiris Pro Payload uses the Smart Dovetail interface for power, data, and control. Pinouts for this connector can be found at both links bellow:
The Wiris video and control is passed through over the ethernet pins on the smart dovetail. Info on communicating with the camera can be found in the document bellow.
The gimbal utilizes Mavlink for control from the aircraft over the UART pins.
The Wiris is powered directly from the gimbal, these specs account for the entire package in operation. Power is drawn from the V_BATT pins on the Smart Dovetail pinout.
Voltage
18-25.2V
Current (Nominal)
0.7-1.5A depending on flight conditions
Current (Max)
5A
The Wiris Pro Payload uses the Smart Dovetail/Pixhawk Payload Bus Quick Release mechanical mount. An overview of the Smart Dovetail, including a 3D CAD model of the Smart Dovetail male and female sides is available here:
You are encouraged to use this model to integrate the Smart Dovetail design into your own UAV! Conversely, you can purchase a Smart Dovetail mount with a 32 x 32mm M3 mounting bolt pattern from Freefly for easy installation:
Refer to the specs section for mass, dimensions, and other information.
For information on the vibration isolation system shipped with Astro Thermal, refer to the section linked bellow.
Isolation systems are aircraft specific and a different system may be optimal for your aircraft, however we offer a couple of options in our store:
This payload is an integrated package that combines the EO and IR camera capabilities of the Wiris Pro with Freefly Systems gimbal stabilization, tuning, and testing. The payload uses the Smart Dovetail open-interface for PX4. The payload has been extensively tested and is natively integrated with the Freefly Astro drone, but it is certainly possible to integrate this payload on to other UAV platforms.
