1.Durandal Flight Controller
The on-board sensor BMI088 on the Durandal has changed to ICM20602 until further notice.
Please note that this change does not affect the usage of the product.
The GPS RGB LED Driver Chip has been updated. This update does not affect Ardupilot users.
For PX4 Autopilot users, you will need to upgrade your PX4 firmware to Stable Release v1.12.2 or newer for LED driver Support.
Durandal is a new flight controller designed by Holybro utilizing the STM32H7 microcontroller series.
As increasing number of drone companies and developers need to run more powerful models and build on more embedded memory capabilities, Durandal is designed to offer the performance upgrade for development needs. The advantage will come in handy with intensive calculation features is required.
Harnessing from our extensive autopilot building experience in the past years, we have implemented new vibration absorption system into the mechanical design of the hardware, and integrated IMU heater for sensors temperator control.
Durandal is pre-installed with PX4, and also supported by other flight stacks such as Ardupilot.
