Navio2 接线与快速开始

本条提供了关于将**NAVIO2**附着在Raspberry Pi上、为其最重要的外围供电和连接的信息。

将NAVIO2附在树莓皮上

Navio2上的ArduPilot正致力于:

  • 草莓派3型B
  • 草莓派2型B

挂载NAVIO2:

  • 将空间器安装到Raspberry Pi的顶端,并用底部的螺丝固定.
  • 连接扩展 你是个40 pin gpio 端口 。
  • 将NAVIO2附于扩展标题。
  • 用螺丝固定NAVIO2.

说明：

Raspberry Pi2需要一个外部的USB Wi-Fi dongle. 有大量受支持的Dongles列表这里.

Powering NAVIO2

Navio2 has three power sources, all of them can be used simultaneously as they are protected by ideal diodes.

For testing and development purposes: Connect 5V 1A power adapter to the Raspberry Pi's microUSB port. Raspberry Pi will provide power to the NAVIO2.

In a drone: NAVIO2 should be powered by a power module connected to the "POWER" port on NAVIO2. NAVIO2 will provide power to the Raspberry Pi.

Redundancy: In case of power module failure NAVIO2 will switch to power from the servo rail.

警告：

All power sources should provide voltage in 4.8-5.3V range, otherwise you can damage your NAVIO2 and Raspberry Pi.

Connect remote control inputs

NAVIO2 supports PPM and SBUS signals as an RC input. To connect receivers that do not support PPM output you can use PPM encoder. PPM receiver is powered by NAVIO2 and does not require power on the servo rail.

警告：

Do not connect servos to the RC receiver! Servos can consume a lot of power which RC receiver port may not be able to provide and that may lead to Raspberry Pi and NAVIO2 shutting down and even getting damaged.

Some of the receivers with PPM output:

For ACCST (most FrSky transmitters):

  • FrSky D4R-II 4ch 2.4Ghz ACCST Receiver
  • FrSKY V8R7-SP ACCST 7 Channel RX with composite PPM
  • FrSKY D8R-XP

For FASST (Futaba & some FrSky transmitters):

  • FrSky TFR4 4ch 2.4Ghz Surface/Air Receiver FASST Compatible

GNSS Antenna

GNSS antenna is plugged into the MCX port on top of NAVIO2.

Connect Motors

ESCs are connected to RC outputs labeled from 1 to 14 on a 2.54mm header.

../../../images/navio2-escs.jpg

For typical ESCs setup schemes visit NAVIO2 documentation which includes copter, plane, rover setups.

说明：

Only one ESC power wire (central) should be connected to Navio2 servo rail, otherwise BECs built in ESCs will heat each other.

Connect other peripherals

Depending on your hardware there may be any number of other peripherals attached, including sensors, cameras, grippers etc.

Telemetry

Radio modems can be connected either over UART or over USB.

  • UART radio

For UART port use /dev/ttyAMA0 serial.

../../../images/navio2-uart-radio.jpg
  • USB radio

Use /dev/ttyUSB0 virtual serial port for USB.

../../../images/navio2-usb-radio.jpg

Servos

Servos are connected to RC outputs labeled from 1 to 14 on a 2.54mm header.

../../../images/navio2-servos.jpg

说明：

Power module does not provide power to servos. To provide power to servos connect BEC to the servo rail. BEC would also serve as back-up power supply to Navio2.
