Holybro Durandal

Overview

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
