Raspberry Pi 5

The Raspberry Pi 5 with 2–3× the speed of the previous generation, and featuring silicon designed in‑house for the best possible performance, we’ve redefined the Raspberry Pi experience. The Pi5 is a versatile Linux development board with a quad-core processor running at 2.4GHz a GPIO header to connect sensors, and the ability to easily add an external microphone or camera - and it's fully supported by Edge Impulse. You'll be able to sample raw data, build models, and deploy trained machine learning models directly from the Studio.

In addition to the Raspberry Pi 5 we recommend that you also add a camera and / or a microphone. Most popular USB webcams and the Camera Module work fine on the development board out of the box.

Setting Up Your Raspberry Pi 5 with the New Bookworm OS

In this documentation, we will detail the steps to set up your Raspberry Pi 5 with the new Bookworm release OS for Edge Impulse. This guide includes headless setup instructions and how to connect to Edge Impulse, along with troubleshooting tips.

1. Connecting to Your Raspberry Pi

Headless Setup

You can set up your Raspberry Pi without a screen. To do so:

1. Download the Raspberry Pi OS - Bookworm Release

   • Ensure you have the latest Raspberry Pi OS which supports the new Edge Impulse Linux CLI version >= 1.3.0.

2. Flash the Raspberry Pi OS Image

   • Flash the OS image to an SD card using a tool like Balena Etcher.

3. Prepare the SD Card

   • After flashing, locate the boot mass-storage device on your computer.

   • Create a new file called wpa_supplicant.conf in the boot drive with the following content:

     Copy

     ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
     update_config=1
     country=<Insert 2 letter ISO 3166-1 country code here>
     
     network={
       ssid="<Name of your wireless LAN>"
       psk="<Password for your wireless LAN>"
     }

     Replace the placeholders with your WiFi credentials.

   • Create an empty file called ssh in the boot drive to enable SSH.

4. Boot the Raspberry Pi

   • Insert the SD card into your Raspberry Pi 5 and power it on.

5. Find the IP Address

   • Locate the IP address of your Raspberry Pi using your router's DHCP logs or a network scanning tool. On macOS or Linux, use:

     Copy

     arp -na | grep -i dc:a6:32

     This will display the IP address, e.g., 192.168.1.19.

6. Connect via SSH

   • Open a terminal and connect to the Raspberry Pi:

     Copy

     ssh pi@192.168.1.19

   • Log in with the default password raspberry.

With a Screen

If you have a screen and a keyboard/mouse attached to your Raspberry Pi:

1. Flash the Raspberry Pi OS Image

   • Flash the OS image to an SD card as described above.

2. Boot the Raspberry Pi

   • Insert the SD card into your Raspberry Pi 5 and power it on.

3. Connect to WiFi

   • Use the graphical interface to connect to your WiFi network.

4. Open a Terminal

   • Click the 'Terminal' icon in the top bar of the Raspberry Pi desktop.
