Flight controllers are the "brains" of an unmanned vehicle. PX4 can run on many flight controller boards.
在选择飞控板时你应当考虑飞机的物理尺寸限制、想要进行的活动以及必不可少的成本。
Pixhawk系列 - 在Nuttx OS上运行PX4的开放式硬件飞行控制器。 有许多外形，有针对许多用例和细分市场的版本。
Pixhawk Standard Autopilots are used as the PX4 reference platform. They are supported and tested by the PX4 development team, and are highly recommended.
Other flight controllers are manufacturer-supported. This includes FCs that are heavily based on the Pixhawk standard (but which are not fully compliant), and many others.
Note that manufacturer-supported controllers can be just as "good" (or better) than those which are Pixhawk-standard.
Dedicated flight controllers like Pixhawk are not usually well-suited for general purpose computing or running computationally intensive tasks. For more computing power, the most common approach is to run those applications on a separate onboard Companion Computer.
Integrated companion computer/flight controller solutions include:
- Holybro Pixhawk RPI CM4 Baseboard
- Other options in Companion Computer > Integrated Companion/Flight Controller Boards
PX4 can also run natively on Raspberry Pi (this approach is not generally considered as "robust" as having a separate companion):
PX4 适用于许多流行的商用无人机产品，包括一些搭载 PX4 以及可以用 PX4 升级的产品（允许您将任务规划和其他 PX4 飞行模式添加至您的无人机）。
