Holybro Durandal (beta) Ardupilot Flight Controller PM07 Power Module UBLOX NEO-M8N GPS for RC Drone Durandal is the latest update to the successful family of Holybro flight controllers. It was designed & developed by Holybro, optimized to run the latest Ardupilot firmware. It features the latest advanced processor technology from STMicroelectronics, sensor technology from Bosch & Inven Sense, & a Chibi OS real-time operating system, delivering incredible performance, flexibility, & reliability for controlling any autonomous vehicle. Durandals STM32H7 microcontroller, running at 480 M Hz, has 2 MB of Flash memory & 1 MB of RAM. With the increased processor power & ample resources, developers can freely implement more complex algorithms & 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 & 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 & six associated chip select lines allow for additional sensors & an SPI-interfaced payload. There are a total of four I2C buses: two dedicated for external use & two grouped with serial ports for GPS/compass modules. The Durandal is the latest update to the successful family of Holybro flight cont
