Raspberry Pi

Raspberry Pi imageThis one (1) Raspberry Pi 4 Model B is a computer you can check out to use at home!

This small barebones computer is perfect for learning programming, messing around with open source software, exploring Linux, tinkering and experimenting, and even installing fresh operating systems.

The Raspberry Pi 4 Model B comes with two (2) Micro SD cards, one loaded with an operating system and one you can tinker with yourself. We can also provide a USB-A keyboard and a USB-A mouse to plug in to get you started. You will have to provide a monitor with an HDMI input.

Choose an operating system

The Raspberry Pi comes with two (2) 32 GB Micro SD cards.

  • BLANK by default
  • Raspberry Pi OS pre-installed (this Micro SD card is often pre-installed)

If you choose the BLANK Micro SD card, see Installing an operating system below.

If you choose the Raspberry PI OS Micro SD card, skip to Insert a Micro SD card below.

Installing an operating system

Install Raspberry Pi Imager

On a different device other than the Library Raspberry Pi computer, install the Raspbery Pi Imager software.

(On other Linux devices, you may be able to open a Terminal command prompt window and enter sudo apt install rpi-imager to install this Raspberry Pi Imager software.)

Use Imager to install an operating system

Plug in a Micro SD card (either your own or the BLANK one provided by the Library in the Kit) into your device.

Open Imager on the computer you installed it on when you have an Internet connection.

Choose what Operating system you want to configure.

Then choose what storage device you want to put it on – find the Micro SD card that you inserted.

Then click WRITE. “WRITE” will download and then write that software to the Micro SD card you chose.

The Imager program lets you know when it is safe to remove the media you installed an operating system onto.

Insert a Micro SD card

The Micro SD card slot is located on the bottom of the computer by the plastic feet. The gold contact points should face up toward the green computer board.

Connect a monitor

Use the included Micro-HDMI to HDMI cable to connect to one monitor.

If you have another Micro-HDMI to HDMI cable, you can use a second monitor at the same time.

Attach accessories

Install accessories like mice, keyboards, and/or flash drives using the tall rectangular USB-A 2.0 and 3.0 plugs. Raspberry Pi OS works with standard plug-and-play mice and keyboards.

Power on

Plug the included USB-C power adapter into the USB-C plug on the Raspberry Pi, and the  other end of the power adapter into a power outlet.

If the Raspberry Pi doesn’t start to power on immediately, press the button near the USB-C plug on the computer on the cable. It should start to turn on and you’ll see a blue

Log in

When you reach the login screen, it should ask for the computer username and password:

For the Micro SD card with Raspberry Pi OS preinstalled:

  • Computer username: pi
  • Password: pi

For the BLANK Micro SD card:

During the process of installing the operating system on the Raspberry Pi, you should be given the opportunity to decide on a username and password. However, if you skipped/missed that step, the default username and password are:

  • Computer username: pi
  • Password: raspberry

Type in your username and password and hit Enter on your keyboard.

General use

Raspberry Pi OS (previously called Rasbian) is a derivative of Debian. Debian itself is based on the Linux kernel.

Left clicking is the main control. Right clicks often pull up options.

The Chromium web browser is installed.

The Raspberry logo in the upper left corner is the equivalent of the Microsoft Windows Start menu. There are a lot of general purpose programs pre-installed in Raspberry Pi OS.


If you are having trouble with the Lincolnwood Library Raspberry Pi 4 Model B, you can:
-Make sure you have loaded a Micro SD card that has an operating system installed on it.
-Make sure the Micro SD card you’re using is plugged in to the device correctly.
-Do not push the button on the power supply which disables power and turns off the Raspberry Pi.
-If the Raspberry Pi doesn’t turn on, try switching the Micro HDMI plug from one port to the other if you’re only using one monitor, or try switching both Micro HDMI plugs (only one included in our kit) if you’re using two monitors.
