Why Use a Raspberry Pi for a Kiosk?

The Raspberry Pi offers several advantages for kiosk set-ups:

  • Affordable – Raspberry Pis start at just $35, providing an inexpensive base for an interactive kiosk or digital sign. Higher spec models provide even more performance for not much more money.
  • Customizable – As an open platform, the Raspberry Pi is highly customizable. You can choose the operating system, software packages and peripherals to construct your perfect kiosk.
  • Compact – At credit card size, the Raspberry Pi takes up very little space, making it easy to incorporate into a kiosk set-up.
  • Energy efficient – The Pi is an extremely energy efficient device, typically using just a few watts of power. This makes it well suited for always-on, low power kiosk installations.

By leveraging these strengths to create an engaging self-service kiosk or interactive sign, the Pi can help improve customer experience in all sorts of environments.

Setting Up Chromium in Kiosk Mode

Chromium is the open source web browser project that shares much of the same code as Google Chrome. The major difference is that Chromium is 100% free software, while Chrome integrates some proprietary Google components.

Using Chromium in kiosk mode provides an easy way to display web content full screen. Kiosk mode locks down the browsing session, preventing users from exiting the app or navigating to other sites.

Setting up Chromium in kiosk mode on a Raspberry Pi takes just a few simple steps:

  1. Install Chromium on the Raspberry Pi

sudo apt install chromium-browser

Open Chromium and navigate to the web page you want to display

Click the settings icon in the top right and select “App Launcher”

In the Application Launcher section, check “Open as Window”

Under Kiosk mode, check “Enable kiosk mode”

Specify any other Kiosk settings, like hiding the cursor

  2. Click “Close” to save the settings

  3. Reopen Chromium to enter kiosk mode automatically

With these steps, Chromium will now automatically launch in a restricted kiosk session, locked to your selected web page.

Customizing the Raspberry Pi Kiosk

A Raspberry Pi based kiosk provides endless opportunities for customization. Here are some ideas to tailor your kiosk to your specific needs:


  • Add a touchscreen for intuitive user interaction
  • Include high-quality audio hardware for music playback or sound effects
  • Connect a receipt printer to distribute coupons or promo codes
  • Add NFC/RFID readers to integrate loyalty programs or access control
  • Attach thermal printers to instantly print guest checks, tickets, or labels


  • Secure the Pi in a robust protective enclosure suited to the installation environment
  • Choose stylish, branded enclosures to complement corporate decor or aesthetics
  • Utilize mounts and racks to neatly organize peripheral devices
  • For a compact, low profile install, opt for enclosures with built-in cable management features

Power Options

  • Power the Pi from main AC outlets for always-on installations
  • Use custom Power over Ethernet (POE) HAT add-ons to eliminate bulky power bricks
  • For short-term or portable setups, integrate high capacity USB power banks

Management & Monitoring

  • Control the Raspberry Pi headlessly over SSH when out of physical reach
  • Attach Uninterruptible Power Supplies (UPS) to protect against power disruption
  • Utilize IP KVM solutions to remotely monitor or manage the Pi device itself
  • Leverage smart plugs for remote power cycling ability

For advanced functionality, multiple Raspberry Pis can even be set up in distributed architectures, with dedicated roles like application front-end, print server, API gateway, etc.

With clever customization, the possibilities are endless!

Recommended Hardware

Here is some recommended hardware for a Raspberry Pi Chromium kiosk setup:

  • Raspberry Pi – The Pi 4 Model B with 4GB RAM delivers plenty of performance for most kiosks
  • Case – Protect the Pi with a well designed case like the Flirc Raspberry Pi 4 Case
  • Power Supply– Reliably power the Pi using an official Raspberry Pi USB-C adapter
  • MicroSD Card – Boot the Pi from a high endurance A2 rated 32GB+ card
  • Display – Choose touchscreens between 7-10″ depending on usage
  • Touch Accessory – Add touch capabilities via HAT add-ons like the Piper Touch Display Interface
  • Audio – Dedicated audio HAT add-ons like the HiFiBerry DAC provide premium sound

Investing in high quality supporting hardware helps ensure reliable, long term operation for any public facing kiosk deployment. Carefully structuring the PI’s peripheral ecosystem is key to delivering engaging experiences.

Kiosk Security & Maintenance

When deploying a public kiosk, implementing proper security and ongoing maintenance best practices is critical:

Software Security

  • Use a Linux OS specialized for kiosk scenarios like Porteous┬áKiosk
  • Configure software to auto-launch in kiosk mode securely
  • Lock down OS permissions to prevent system tampering
  • Ensure all software & libraries are kept fully updated

Physical Security

  • Fasten Raspberry Pi hardware securely inside a robust enclosure
  • Use locks and tamper-resistant fasteners to discourage device access
  • Mount kiosk firmly behind secure panels or out of arm’s reach
  • Install security cameras to actively monitor kiosk usage

Network Security

  • Assign static internal IPs for fleet management & oversight
  • Limit network connectivity via firewall policies
  • Utilize VPN tunnels to isolate sensitive traffic flows
  • Deploy gateway anti-malware tools to analyze traffic

Monitoring & Alerting

  • Track device health metrics like thermals, disk space, etc
  • Create alarms for events like application crashes
  • Monitor application state to ensure uptime
  • Use remote power cycling to self-heal frozen devices

Failover & Recovery

  • Structure redundant devices to takeover if primary kiosk fails
  • Enable auto-restore mechanisms to return to known good state
  • Maintain regular backups of writeable data & configuration
  • Setup remote reimaging workflows to quickly restore devices

Carefully implementing measures like these helps enable reliable, secure kiosk operation. However, some manual maintenance will always remain necessary – like occasional hardware inspections, enclosure surface cleaning, application updates, OS patching, etc. Budgeting for proper deployment and lifecycle management is key for long term success.
