Holybro Durandal

Durandal is the latest update to the successful family of Holybro flight controllers. It was designed and developed by Holybro, optimized to run the latest Ardupilot firmware.
It features the latest advanced processor technology from STMicroelectronics®, sensor technology from Bosch® and InvenSense®, and a ChibiOS real-time operating system, delivering incredible performance, flexibility, and reliability for controlling any autonomous vehicle.
Durandal’s STM32H7 microcontroller, running at 400MHz, has 2 MB of Flash memory and 1 MB of RAM. With the increased processor power and ample resources, developers can freely implement more complex algorithms and models on the autopilot.
Dual high-performance, low-noise IMUs on board are designed for demanding stabilization applications. Data-ready signals from all sensors are routed to separate interrupt and timer capture pins on the autopilot, permitting precise time-stamping of sensor data. Newly designed vibration isolation enables more accurate readings, allowing vehicles to achieve better overall flight performance.
The two external SPI buses and six associated chip select lines allow for additional sensors and an SPI-interfaced payload. There are a total of four I2C buses: two dedicated for external use and two grouped with serial ports for GPS/compass modules.
The Durandal is the latest update to the successful family of Holybro flight controllers. The Durandal autopilot development kit is perfect for developers at corporate research labs, startups, and for academics. Durandal: the cutting edge autopilot.

This is a very nice looking Autopilot , it’s great too see a lot of thought and design had gone in and not just another clone of others.

Also having detailed technical information published is fantastic too and should be the norm for all.

Looks to be a very good controller this.
