Materials Required

You'll need a mouse, keyboard, monitor, wall adapter with minimum power requirements, and cables to begin. Once configured, the Pi can be operated from its own peripherals or another computer connected over the Internet.

Kit Versions

There are three versions of the kit available at SparkFun. Each version includes a Raspberry Pi 4 with a different size RAM. Check out below for the different kit versions available!

Basic Kit Version

The basic kit offers the bare bones of what you need to get up and running. This is assuming that you have a monitor, keyboard, mouse, and card reader [1] on hand. The connectors are different on the Pi 4 so the kit provides a mini-HDMI to HDMI cable and USB-C wall adapter at a minimum. The kits include a raw microSD card and SD card adapter so that you can flash your favorite Linux distribution. Last, a Qwiic Shim is included to easily connect a I2C device to the Raspberry Pi.

Desktop Kit Version

The desktop kit is pretty much the basic. However, a wireless keyboard with touchpad is included. We also include a heat sink case to keep your Pi cool as a cucumber when pushing your Pi's processing capabilities. The power supply included in this kit is provides a modular power system with the USB Type C wall adapter and Type C to Type C USB cable. Compared to the basic kit, the raw microSD card [1] included in this kit has a faster read/write speeds to take advantage of the Pi 4's processing power. This cuts the amount of time to flash or update the Linux distribution of your choice down significantly.

Getting an OS

The microSD card included in each kit does not have an image flashed. You'll need to flash a new image to the microSD card if you are just starting out or if your existing image becomes corrupt somewhere down the line. There are a few Linux-based images available depending on your application. Or feel free to power down your Pi and switch microSD cards out to experiment with a different image. For beginners, we recommend getting NOOBS. Otherwise, the Raspbian with the PIXEL desktop would be the best.

  • NOOBS (i.e. New Out-Of-the Box Software) - Contains Raspbian and LibreELEC. Other images can also be downloaded from the internet and installed.
  • Raspbian - Official Raspberry Pi Debian-based computer operating system. There are three downloads. We recommend the desktop version with recommended software. The other downloads are the same but with less software. For advanced users, Raspbian Lite is the minimal text-only version and requires users to navigate using the command line interface (CLI).
  • Other 3rd Party OS Images - There are other distributions available from third-party. If you are feeling adventurous, check out the other images available!

For the scope of this tutorial, we will summarize two of the images from the Pi foundation.

Flashing the Image NOOBS

If you decide to use NOOBS, you will need to:

  • Insert the microSD card into a card reader.
  • Download the ZIP file for NOOBS.


  • Extract the ZIP file.
  • Format your Raspberry Pi's microSD card if needed.
  • Copy all the contents from the unzipped folder into the microSD card.
  • Eject the microSD card from your computer.

Flashing the Image Raspbian and 3rd Party OS Images

Then follow the steps below to flash an image using the Raspberry Pi Imager.

  • Insert the microSD card and card reader into your computer's port.
  • Open the software imaging tool [2] of your choice (in this case, we'll use the Raspberry Pi Imager for your OS but you can use other images as well).


  • Press CHOOSE OS to select the Operating System from the list (in this case, we'll use one of the Raspbian images but you could use any of the 3rd party images ).
  • Press CHOOSE SD CARD to select mounted microSD Card.
  • Press Write (it will take a while depending on the image and microSD card so just do a little dance as you wait).
  • Eject the microSD card when finished.

Assembly

The Pi is straight-forward and easy to put together, but in the event that something doesn't seem right, this section will give you an idea of what it is supposed to look like to get the Pi up and running.

Unbox and gather these components before beginning the assembly

Attaching a Heat Sink Enclosure Optional

If you are using the heat sink enclosure, grab the thermal pad that matches the size of the Pi's CPU. Remove the thin, clear plastic film and paper from both sides of the thermal pad. Attach the side that had the paper to the Pi's CPU. There are thermal pads shaped for other IC and can be added on those chips as well. However, those do not get hot.

Thermal Pad

Grab the top of the heat sink case with the cutout for the GPIO pins and place it on the Pi. If you are using the DSI port or Raspberry Pi camera, now would be good time to insert the ribbon cable between the Pi and the top of the heat sink.

Top of Heat Sink

Align the mounting holes of the bottom of the heat sink case.

Attaching Peripherals

Attach desired consumer computer equipment. At a minimum to get up and running or navigate through the Pi, we recommend using a monitor, keyboard, and mouse. The following images will use a Pi without an enclosure to show where to connect the peripherals.

Monitor

Using a monitor with a HDMI port [3], insert the HDMI end of the cable to the connector. Then connect the mini-HDMI end of the cable to the connector. Note that the Pi 4 has two mini-HDMI outputs. You will need to connect to the HDMI0 port. closest to the USB-C connector.

mini-HDMI Cable to Pi

Keyboard and Mouse

Connect a keyboard and mouse to the USB ports. In this case, we were using a wireless keyboard and mouse that had a USB dongle. While you can insert the HID device into any USB port, we recommend connecting it to the USB 2.0 port so that you have the faster USB 3.0 ports (with blue) are available for certain devices (i.e. flash drives).

Wireless USB Dongle for Keyboard and Mouse

If you are using a wireless keyboard/mouse combo, the wireless USB dongle that is included maybe hidden in the battery compartment. If you are using the Logitech K400 Plus, flip it over and slide the compartment for the battery holder off.

Slide Cover Off Battery Compartment Logitech K400

Flipping over the cover, you'll notice that the dongle is attached inconspicuously on the back. Grab the wireless dongle from the back to insert into the Pi's USB port and slide the cover back on the Logitech K400 Plus.

Hidden Dongle on Logitech K400

To power the keyboard, make sure to flip the power switch to the green position on the side of the Logitech K400 Plus. Feel free to flip the power switch back to the red position to remove power.

Flip Switch to On Position

Power Supply

If you have not already, make sure that you inserted the microSD card into the microSD socket. Once everything is connected, insert the power supply [4]!

Power Up the Pi

Completed Setup

At this point, your setup should look similar to the images below to get the Pi up and running. You could add ethernet, a second monitor, headphones, speakers, or a camera depending on your setup as well!

Connecting Hardware

Need easy access to the GPIO pins on the board? If you ordered a Qwiic cable, Qwiic enabled device, and any of the kits, take a look at the Qwiic SHIM [5] to quickly access the I2C pins. If you are looking to use certain I2C devices with Python, we recommend taking a look at the Qwiic Kit for Raspberry Pi to get started.

Headless Raspberry Pi Setup

April 23, 2018

Configure a Raspberry Pi without a keyboard, mouse, or monitor.

Methods of Working with the Pi

Once the Pi is configured, there are a few methods of using it depending on if you want to use it like a desktop or manage it remotely.

This section covers using the Pi in the following ways

  • Using HDMI-out with Monitor -- Operate your Pi like a desktop computer.
  • Headless without a Monitor
    • Using the serial terminal -- Some functionality.
    • Using SSH -- Operate through a network linked to another computer.
    • Using VNC -- Control the Pi's graphical desktop remotely over the Internet using a computer. This is useful if you decide to remotely connect to a Pi that may or may not be connected to a monitor.

Using HDMI-out with a Monitor

If this is the first time you are booting NOOBS, you'll need to connect your Raspberry Pi to a monitor and follow the installer. In the window, select Raspbian Full [RECOMMENDED] and click on the button to Install. You'll need to be patient as the software installs the OS to the microSD card. Once finished, click on OK. This will restart the Pi.

PIXEL Desktop (GUI)

By selecting NOOBS with Raspbian, it automatically logs in and starts a graphical user interface. Once the desktop installs, follow the wizard to configure your Raspberry Pi! You'll need to configure the settings based on your region, monitor, internet settings, and password. It is best to have the Pi check for updates and restart for the changes to take effect.

Set Up Wizard

Command Line Interface (CLI)

If configured to boot to shell, log in with the following credentials:

     username: pi
     password: raspberry

Then, enter in the command line to enter a graphical environment should you decide to take advantage of the desktop-type menu-driven operating system.

language:bash
startx

If you need to get back to text land, you can either

  • Log off through the Task Bar Menu
    • drops back to the shell, closing down the X window system
  • Open xterm from the Task Bar
    • opens a shell in a graphical window
  • Use CTRL+ALT+1 through CTRL+ALT+8
    • gives you a number of shells, with 7 being the graphic environment (if loaded).

Remember, shutdown with the task bar menu or enter the following command from a shell, and wait for the system to halt before removing power [6].

language:bash
sudo shutdown -h now

Headless without a Monitor

As an alternative, you can also log into the Pi as a "headless" computer. This is basically a Raspberry Pi without a monitor, keyboard, or mouse. You can decide to connect to the Pi using a serial UART or SSH. For advanced users, you will need to turn on the interfaces before you can take advantage of these setups.

How to Use Remote Desktop on the Raspberry Pi with VNC

July 9, 2018

Use RealVNC to connect to your Raspberry Pi to control the graphical desktop remotely across the network.

Configuring the Pi

This section goes over configuring the keyboard, wired, and wireless internet.

The Raspbian distribution comes defaulted to European hardware. With US keyboards, the " (quotation mark) symbol is replaced by @ (commercial at) and our number sign # is replaced by the European pound sign £. This can make it aggravating when trying to #define things.

PIXEL Desktop (GUI)

The easiest method of configuring the Pi is using the PIXEL desktop. For those that need to adjust the settings again after the initial setup, check below!

Configuring the Keyboard Layout

To configure the keyboard layout again, head to the Task Bar Menu by clicking the Pi Start Menu > Preferences > Raspberry Pi Configuration > Localisation.

Configuring the Internet Interfaces

Raspbian does a good job of configuring wireless networks automatically. By default, DHCP is configured so that the Pi will receive an IP address when a network cable is plugged it to the Ethernet port or when a wireless network is connected.

To use the graphical network tool, right click on the icon on the right side of the task bar, and click "WiFi Networks (dhcpcdui) Settings". Then, select the interface desired (wlan0 or eth0) to disable the DHCP and set your own IP, if necessary.

To connect to a wireless network, click on the icon, select the desired network, and enter the password.

Hovering over the icon will bring up a status of wlan0 and eth0 that also shows the IP address.

Command Line Interface (CLI)

For advanced users using the command line, you can use the CLI to adjust the settings.

Configuring the Keyboard Layout

Invoke the config tool with the following command in the command line:

language:bash
sudo raspi-config

Then take the following actions:

  • Set the default locale for the system
    • Select "Internationalisation Options"
    • Select "Change Locale"
    • Deselect en_GB.UTF-8 UTF-8
    • Select en_US.UTF-8 UTF-8, (Ok)
    • Set default to en_US.UTF-8, (Ok)

  • Change the keyboard layout -- from the Internationalisation Options menu,
    • Change Keyboard Layout
    • Leave set as: Generic 105-key (Intl) PC (Ok)
    • Select Other (Ok)
    • Select English (US) (Ok)
    • Select English (US) (Ok)
    • Select default (Ok)
    • Select No compose key (Ok)
    • Set Ctrl+Alt+Bksp function (Ok)

  • Finish with the dialog and get back to the shell
    • Try the " and # keys at the prompt.

We recommend restarting the Pi at this point to ensure that the changes take effect.

Configuring the Internet Interfaces

At this time, the network configuration works out of the box so there's really nothing to configure, but in case something goes awry, here's the basics of what can be played with and a known-working configuration to compare with.

A configuration file, interfaces, configures both wired and wireless devices. Enter the following command into a terminal to edit the interfaces file.

language:bash
sudo nano /etc/network/interfaces

Replace "nano" with "leafpad" if you prefer graphics. Here's what our Pi 3 is using:

language:bash
# interfaces(5) file used by ifup(8) and ifdown(8)

# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'

# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d

auto lo
iface lo inet loopback

iface eth0 inet manual

allow-hotplug wlan0
iface wlan0 inet manual
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

allow-hotplug wlan1
iface wlan1 inet manual
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

By default, this file is set up to get its configuration from /etc/wpa_supplicant/wpa_supplicant.conf, which is really the proper place for wifi information. Here are the contents:

language:bash
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
        ssid="myNetworkSSID"
        psk="mySuperSecurePassword"
        key_mgmt=WPA-PSK
}
A note on network configuration: Try the GUI tool first, and only modify the files as a last resort. If you find the tool doesn't work, save your configuration files as a backup, and don't be afraid to try your hand at a manual configuration.

Applying the Changes

Sometimes the link should be cycled for a new configuration to take. Rather than shutting down the pi and restarting, use ifdown and ifup to bring the link down and back up.

For wireless connections, use

language:bash
sudo ifdown wlan

and

language:bash
sudo ifup wlan0

For wired connections, use

language:bash
sudo ifdown eth0

and

language:bash
sudo ifup eth0
