Holybro Durandal

:::warning PX4 does not manufacture this (or any) autopilot. Contact the manufacturer for hardware support or compliance issues. :::

Durandal^® is the latest update to the successful family of Holybro flight controllers. It was designed and developed by Holybro.

At high level, some of the key features are:

Integrated temperature control for sensors.
Powerful STM32H7 microcontroller running at 480MHz. 2 MB of Flash memory and 1 MB of RAM.
New sensors with higher temperature stability.
Internal vibration isolation system.
Dual high-performance, low-noise IMUs on board are designed for demanding stabilization applications.

A summary of the key features, assembly, and purchase links can be found below.

:::note This flight controller is manufacturer supported. :::

组装 / 设置

The Durandal Wiring Quick Start provides instructions on how to assemble required/important peripherals including GPS, Power Management Board etc.

编译固件

端口使用标准的串口针脚，可以连接到标准的 FTDI 连接线上（3.3V，但它有5V 耐受性），或连接到 Dronecode probe 上。针脚定义使用标准的 Dronecode 调试连接器针脚定义。有关如何连接此端口的详细信息，请参阅接线页面。

任何可用普通RC伺服系统或Futaba S-Bus伺服系统控制的多旋翼、固定翼、无人机、无人船。

Debug调试端口

全部可支持的机型可见机型参考。

The port has a standard serial pinout and can be connected to a standard FTDI cable (3.3V, but it's 5V tolerant) or a Dronecode probe. The pinout uses the standard Dronecode debug connector pinout. Please refer to the wiring page for details of how to wire up this port.

:::note No Debug port is exposed for the I/O board. :::

外部设备

数字空速传感器
数传电台模块
测距仪/距离传感器

支持的平台/机身

Any multicopter / airplane / rover or boat that can be controlled with normal RC servos or Futaba S-Bus servos.

The complete set of supported configurations can be seen in the Airframes Reference.
