Flight Controllers

Contact Us

    Durandal is a flight controller designed by Holybro utilizing the STM32H7 microcontroller series. It comes with built-in vibration isolation system and integrated IMU heater for sensors temperature control. 

     

    Key Design Points:

    • High performance H7 Processor with clock speed up to 480 MHz
    • Redundant inertial measurement unit (IMU) from Bosch® & InvenSense®
    • Built-in Vibration isolation system to filter out high frequency vibration and reduce noise to ensure accurate readings
    • IMUs are temperature-controlled by onboard heating resistors, allowing optimum working temperature of IMUs
    • 2 power ports & 5 general purpose serial ports
    • Two Power ports for redundancy
