Insight
A flight controller is the central unit of a drone, managing stability, navigation, and flight performance. It processes sensor data (accelerometer, gyroscope, GPS) to control orientation and altitude, interprets commands, and ensures smooth operation. It connects to peripherals like ESCs and cameras, enabling reliable and precise drone control.
Advanced flight controllers often support multiple interfaces, such as PWM, I2C, SPI, and CAN, enabling versatile connectivity. With features like real-time processing, failsafe mechanisms, and compatibility with a wide range of drones, the flight controller is a crucial component for enabling stable and reliable flight operations.
