I have a question about Navio2 and raspberry pi

Hi @osung1598,

@osung1598

I want to buy a socket that connects uart, i2c, adc, and power on Navio2, but I couldn’t find it, so I’m asking here.
I would appreciate it if you could tell me the name and specifications of the socket connected to Navio2.

For UART and ADC ports, you can use a DF13 6-pin connector. For the I2C port, DF13 4-pin. I believe the pinout scheme might be of help to you.

We also sell the wire pack that you can check in our store.

I wonder what role the raspberry pi that connects to Navio2
I asked the community that when the mission is handed over from the mission planner to Navio2, it is stored in Navio2’s memory.
(If not, tell me what happens.)
Then, I wonder what role raspberry pi plays.
Please explain in detail what role Navio2 and raspberry pi each play.

Let me give you a brief overview.

Navio2 is a HAT for Raspberry Pi. It means that the main computations are happening on the Raspberry Pi. Its capacities are used for running the ArduPilot’s software that Navio2 provides the sensor data for.

If you control the drone manually, you can send the commands to it via the telemetry link. GCS software - for example, Mission Planner - helps you to prepare your vehicle and control the data from it in real-time.

To prepare for an autonomous flight, you need to use your GCS software. In Mission Planner, you can do it in the Flight Plan. Here’s the guide about it. It’s not necessary to load the mission to your autopilot as you can just connect your vehicle and run the mission.

However, you can load the mission to the ArduPilot in a file by configuring it in Mission Planner. In this case, the data is stored in EEPROM, as mentioned here. Please note that you need to set all the parameters before loading it onto your vehicle. It’s also necessary to set the flight mode to AUTO so that the ArduPilot could run the mission autonomously.

I wonder where the motor output connected to Navio2 is involved.
The pin connected to the motor is in Navio2, but I wonder if Navio2 commands the output to the motor or raspberry pi commands the output to the motor.

The motors are controlled by the ArduPilot software. The Ardupilot is run on the Raspberry Pi. Navio2 then executes these commands.

I can see that you’re in the conversation with Marc in this thread. It’d be great to continue communication there. This way, we’ll keep all details in one thread and avoid doubling of the threads.
