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

Software

Usage

Setup

Refer to Getting Started - Raspberry Pi Documentation.

...

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@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.

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