Function
The board merges together three modules:
- Visual Positioning System - receiving and interpreting data from bottom camera and ultrasonic sonar for flight stabilization.
- Intelligent Flight - using data from cameras for collision detection and object tracking.
- OFDM transciever - receiving commands from Remote Controller, and transmitting telemetry data plus compressed video stream for FPV.
