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
