Flight Controller

This is the central “brain” of the quadcopter.  Flight controllers come in many varieties, but the most popular are based on the STM32 processor.  This is the central unit that does the motor speed calculations and then outputs that calculation to the esc for motor speed control.  The Flight controller uses sensors such as accelerometers and gyroscopes to determine the quadcopter’s position in space and then  using a variety of algorithms, determines what the motor speed should be and outputs that information for the motor speed controllers.
