Durandal is a new flight controller utilizing the STM32H7 microcontroller series

Holybro designed a new flight controller that utilizes the STM32H7 microcontroller series. As increasing numbers of drone companies and developers need to run more powerful models and build on more embedded memory capabilities, Durandal is designed to offer more performance for development needs.

Holybro harnessed from their extensive autopilot building experience in the past years and implemented a new vibration absorption system into the mechanical design of the hardware as well as integrated an IMU heater for sensors temperature control. Durandal is pre-installed with PX4 and is also supported by other flight stacks such as Ardupilot.
