# Holybro Pix32 v5

PX4 does not manufacture this (or any) autopilot. Contact the [manufacturer](https://shop.holybro.com/) for hardware support or compliance issues. 它基于 [Pixhawk 项目](https://pixhawk.org/) 的 **FMUv5** 开放硬件设计,在 [NuttX](http://nuttx.org) 操作系统上运行 PX4。

Pix32 v5 (opens new window)® is an advanced autopilot flight controller designed and made by Holybro®. It is optimized to run on PX4 firmware, which is intended for both academic and commercial developers. It is based on the Pixhawk-project (opens new window) FMUv5 open hardware design and runs PX4 on the NuttX (opens new window) OS. It can be regarded as a variant version of Pixhawk4.

The Pix32 v5 is designed for pilots who need a high power, flexible and customisable flight control system. It is comprised of a separate flight controller and carrier (base) board, which are connected by a 100pin connector. This design allows users to either select a base board made by Holybro, or customize their own.

# 额定电压

Pix32 v5 can be triple-redundant on the power supply if three power sources are supplied. The three power rails are: POWER1, POWER2 and USB.

注解

The output power rails FMU PWM OUT and I/O PWM OUT (0V to 36V) do not power the flight controller board (and are not powered by it). You must supply power to one of POWER1, POWER2 or USB or the board will be unpowered.

Normal Operation Maximum Ratings

Under these conditions all power sources will be used in this order to power the system:

  1. POWER1POWER2 输入电压(4.9 v 至 5.5 v)
  2. USB 输入电压(4.75 v 至 5.25 v)

Absolute Maximum Ratings

Under these conditions the system will not draw any power (will not be operational), but will remain intact.

  1. POWER1POWER2 输入(可运行范围 4.1V 至 5.7V,0V 至 10V 不会损坏)
  2. USB 输入(可运行范围 4.1V 至 5.7V,0V 至 6V 不会损坏)
  3. 舵机输入:FMU PWM OUTI/O PWM OUT 的 VDD_SERVO 针脚 (0V 至 42V 不会损坏)

# 编译固件

提示

Most users will not need to build this firmware! It is pre-built and automatically installed by QGroundControl when appropriate hardware is connected.

To build PX4 for this target:

make holybro_pix32v5_default

# 调试接口

The system's serial console and SWD interface runs on the FMU Debug port
