Flight controllers are the "brains" of an unmanned vehicle. PX4 can run on many flight controller boards.
# Pixhawk 系列
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.
# Manufacturer-supported Controllers
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 consider as "robust" as having a separate companion):
# 可运行 PX4 的商业无人机
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）。
