Double 3

Double 3 is a fully integrated hardware solution, designed with developers in mind, and based on the latest industry-standard cameras, sensors, and GPU technology. A modular software architecture allows third-party developers to utilize the high-level autonomous features, while still having access to the low-level sensor data, if needed. The developer API is available on all D3 devices.

External Ports & Mounting

In addition to the software API, Double 3 has the following external ports and mounting features:

  • Two USB 3.2 SuperSpeed Ports
  • Two mounting holes on the top hidden under the trim, 75mm apart, with #8-32 threads and 5mm max thread depth.
  • One mounting hole on the back behind the access panel above the USB ports, with #8-32 threads and 5mm max thread depth.

Future ROS Integration

Although Double 3 does not use ROS or other similar development libraries, the API architecture does allow for ROS to be implemented, and we may offer ROS connectors in the future.
