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

  • 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

Raspberry Pi 4 (not Raspberry Pi 5) pictured below, however they have the same inputs and outputs.

...

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

First-time setup

1. On your laptop or another computer, download the Raspberry Pi OS onto a SD card (with capacity greater than 32GB). Follow https://projects.raspberrypi.org/en/projects/raspberry-pi-setting-up/2.

2. Go to sudo raspi-config to enable serial UART, SSH, and Camera, if applicable. Search up on google how to do it, there are tons of websites for tutorials.

3. Create an account named warg with the same password as the WARG laptop

   Code Block
   language bash
   sudo useradd warg sudo passwd warg # prompt to enter the password...

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.

...

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

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

   Code Block
   ssh@[IP Address]ssh warg@raspberrypi.local

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

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

   Code Block
   <warg>@<[IP Address]warg@raspberrypi.local ~ $

VNC

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

Refer to https://www.raspberrypi.com/documentation/computers/remote-access.html#screen-share-with-vnc.

Note: VNC Viewer has not been installed. If you want to view the Pi GUI (and see the log images from the WARG laptop), please install it.

You can follow this small video https://youtu.be/NWBmYnNvN3A?t=150 and download VNC viewer from here https://www.realvnc.com/en/connect/download/viewer/windows/
