Raspberry Pi hardware - Raspberry Pi Documentation

When mounting the RPI 5 (or any RPI) on Houston, ensure that:

• Spacers are added between the bottom of the RPI and the metal plate to prevent components from shorting and rubbing against the metal plate.

  • 2x regular M2 nuts can be stacked on top of each other to create this space

  • can also add yellow double sided sealant tape to create this space (optional)

  • a spacer can also be 3D printed

• M2 screws are used to secure the RPI

• Nylon lock nuts are used to fasten down the RPI so that the RPI does not come loose during flight

Electrical

• Power Supply

  • https://github.com/raspberrypi/documentation/blob/develop/documentation/asciidoc/computers/raspberry-pi/power-supplies.adoc

  • Recommended to support full pheripherals is 5V 5A

  • can use 5V 3A power supply if peripheral current draw is less than 600mA

• Internally Designed Solutions

  • 12V->5V @ 5A Buck Converter Board or any other 5V/5A power supply

  • RPi Interface

Software

Usage

Setup

Refer to Getting Started - Raspberry Pi Documentation.

Connect peripherals (e.g. mouse, keyboard, monitor) and networking (e.g. ethernet) to the Raspberry Pi, and then connect it to power, which can be supplied by a cable or directly through its header.

The Raspberry Pi may use microHDMI for video output. Adapters and cables are available.

SSH

The Secure Shell (SSH) protocol is a method for securely sending commands from your computer to the Raspberry Pi over the same network. Note that the Raspberry Pi must be connected to Wi-Fi, it will automatically connect to available known networks on boot - you have to connect it to a hotspot during the flight test before leaving the bay.

Refer to https://www.raspberrypi.com/documentation/computers/remote-access.html.

On the Raspberry Pi:

1. Connect the Raspberry Pi to the internet.

2. From the Preferences menu, launch Raspberry Pi Configuration.

3. Navigate to the Interfaces tab.

4. Select Enabled next to SSH.

5. Click OK.

6. Get the IP address of the Raspberry Pi.

   1. Use one of the methods listed here: https://www.raspberrypi.com/documentation/computers/remote-access.html#find-the-ip-address-of-your-raspberry-pi.

On your remote machine:

1. Connect to the same network as the Raspberry Pi.

2. SSH into the Raspberry Pi using the following command:

   ssh warg@[IP Address]

3. Enter the WARG password (same as WARG Laptop).

4. You should now see the Raspberry Pi command prompt in your terminal.

   <warg>@<[IP Address] ~ $

VNC

Virtual Network Computing (VNC) allows you to control the desktop of one device from another.
