A flight controller is essentially the brain of the drone. It is a small circuit board equipped with sensors and software that processes data to control the drone’s movement. The flight controller interprets pilot commands, processes data from various sensors (such as gyroscopes and accelerometers), and sends signals to the drone’s motors to ensure it flies as expected. visit - https://hcrobo.com/understanding-the-role-of-a-flight-controller-for-drones-a-beginners-guide/ »
