F21AP is a high-performance UAV flight controller that supports helicopters, fixed-wing and other UAV platforms. It adopts dual high-performance MCUs and sensor redundancy design. It has functions such as integrated navigation, flight control, mission management, and measurement and control communication.
F21APUAV flight control is based on the mature
F20AP technology platform, adding a wide voltage and high reliability isolated power supply circuit, high-speed Ethernet interface and independent CAN communication interface, and an internal airspeed meter, which greatly improves the integration of the flight control system , scalability and anti-electromagnetic interference capability
