In this Howchoo guide, I'll show you how to build your own NHL scoreboard that automatically displays live game data for your favorite hockey team!

The purpose of this guide is not only to combine hockey and technology, but to teach you how to work with and control LED panels using a Raspberry Pi computer. Armed with this knowledge, you can create all kinds of displays. :)

This is a beginner-friendly, mostly plug-and-play project that should take about an hour to complete.

How it works

To make everything work, we'll connect a small Raspberry Pi computer to a 64x32 LED panel using a small breakout board. (We use the same panel in our Raspberry Pi LED matrix panel guide.)

Then, we'll use the nhl-led-scoreboard library to automatically retrieve your favorite team's current and upcoming game data. When a game is in play, it will show the current period, score, game clock, and even an animation when a team scores. Not a hockey fan? There are MLB and Fantasy Football libraries too.

Everything is housed in a 3D-printed enclosure. The enclosure is optional; you can also mount the components directly to the back of the panel or set them behind it. If you don't have a 3D printer and still want the enclosure, there are other ways to get it printed.

Final score
When I took this there was no Lightning game on, so I thought I'd support our Florida brothers.

When your team is playing, the scoreboard automatically displays up-to-the-minute game stats including period, score, and game clock.

Raspberry Pi NHL Display Pre-Game Info

On gameday, the scoreboard will show the upcoming matchup as well as the game time. On days when there is no game, a customizable message is shown. In the future, I'd like to modify this to display a clock and local weather data.

Postgame info

The scoreboard even shows post-game data for the previous game.

Adafruit 64x32 LED panel

For this project, you'll need a Raspberry Pi, LED panel, and a few other things.

LED panel

I chose the large 64x32 RGB LED matrix from Adafruit. This panel features a 5mm pitch, meaning the LEDs are spaced 5mm apart. You can also use a smaller display; for example, a 64x32 LED panel with a 3mm pitch is physically smaller (and thus has a higher resolution) than one with a 5mm pitch. Adafruit makes 3mm, 4mm, 5mm, and 6mm pitch panels in the 64x32 variant. You'll also need this amply power supply to run your panel.

"Pitch" refers to the distance between LEDs: "5mm pitch" means the LEDs are 5mm apart.

If you'd like to save money, you can certainly order a cheaper panel elsewhere but I prefer Adafruit displays because they're known for quality.

Raspberry Pi

Although any Raspberry Pi model will work, I chose the Raspberry Pi Zero WH since it's small and inexpensive. If you don't have a soldering iron, be sure to pick up the Zero W_H_ (With Header), which comes with the header pre-soldered. This RGB matrix bonnet fits onto the Raspberry Pi and allows it to easily control the LED panel.


I 3D printed a housing for my panel; the housing is totally optional in case you don't have access to a 3D printer. The panel comes with magnetic feet in case you want to simply stick it somewhere or prop it up on your shelf.

Project cost

The total cost for this project is around $100-125, assuming you use the nice Adafruit panel I did.

Insert the micro SD card into your computer. Then, download and install Raspbian Buster Lite from the Raspbian downloads page.

Be sure to download the Lite version of Raspbian. The GUI in the "full" version of Raspbian uses too many system resources; we need these precious resources to drive our panel, especially on the tiny Zero W.

Next, set up WiFi and enable SSH. When you're done, eject the micro SD card from your computer and put it into the Raspberry Pi.

Raspberry Pi Hockey Scoreboard Wiring

Slide the RGB bonnet onto your Raspberry Pi's GPIO header. I used a few standoffs from a small kit I bought on Amazon, but these are optional.

Next, connect the gray ribbon cable between the bonnet and the panel's JIN1 port.

The panel came with a Y-cable with two white connectors on one end and two "pitchfork" connectors on the other. Connect one of the white connectors to the back of the panel. Then, use a small flathead screwdriver to connect:

  • The red wire's pitchfork connector to the positive (+) terminal on the bonnet
  • The black wire's pitchfork connector to the negative (-) terminal on the bonnet

Finally, connect the power supply to the bonnet. The power supply will power both the Raspberry Pi and LED display. Your Raspberry Pi will now boot.

Coding the scoreboard up

Next, we'll install the nhl-led-scoreboard library. This library will retrieve game data from the Unofficial NHL API and display it on the screen. A special thanks to riffnshred on GitHub for putting this together (and for approving my pull requests)! :)

I'll outline these instructions briefly below, but since these instructions can change, I recommend reading through and following the instructions in the README file on GitHub to check for changes.

Connect to your Raspberry Pi via SSH. After logging in, I recommend changing the Pi's default password and, if you have multiple Pis in the house, changing the Pi's hostname. I changed my hostname to scoreboard so now I log in using ssh pi@scoreboard.

Update the Pi and install Git

sudo apt-get update
sudo apt-get install git python-pip

Install the library and dependencies

git clone --recursive
cd nhl-led-scoreboard/
sudo chmod +x
sudo ./

Set your favorite team

sudo nano config.json

Grab your favorite team's ID from the table below and populate it after fav_team_id:

    "end_of_day": "12:00",
    "debug": false,
    "fav_team_id": 14
Team ID Team ID
Anaheim Ducks 24 Nashville Predators 18
Arizona Coyotes 53 New Jersey Devils 1
Boston Bruins 6 New York Islanders 2
Buffalo Sabres 7 New York Rangers 3
Calgary Flames 20 Ottawa Senators 9
Carolina Hurricanes 12 Philadelphia Flyers 4
Chicago Blackhawks 16 Pittsburgh Penguins 5
Colorado Avalanche 21 San Jose Sharks 28
Columbus Blue Jackets 29 St Louis Blues 19
Dallas Stars 25 Tampa Bay Lightning 14
Detroit Red Wings 17 Toronto Maple Leafs 10
Edmonton Oilers 22 Vancouver Canucks 23
Florida Panthers 13 Vegas Golden Knights 54
Los Angeles Kings 26 Washington Capitals 15
Minnesota Wild 30 Winnipeg Jets 52
Montreal Canadiens 8

Then, save and exit.

Raspberry Pi timezone config

Since the display will show the start time for an upcoming game, you'll need to change your Pi timezone. Otherwise, the game start time will be based on the timezone where the Raspberry Pi is manufactured (the UK).

You'll be prompted to restart after saving your configuration changes.

Testing LED panel

To test your display, run the following command:

sudo python --led-gpio-mapping=adafruit-hat --led-brightness=60 --led-slowdown-gpio=2

You can adjust the brightness to your liking; enter a percentage value from 1 to 100. For example, this outputs full (100%) brightness:

sudo python --led-gpio-mapping=adafruit-hat --led-brightness=100 --led-slowdown-gpio=2

It would be cool to add a potentiometer to the display in the future to adjust brightness on the fly.

The display should now show today's game data or a message stating there's no game today. For additional LED panel configuration options, check out the rpi-rgb-led-matrix library that this project uses under the hood.

Adafruit anti-flicker mod jumper wire
The tiny jumper is soldered between pins 4 and 18.

By default, a bit of flickering can occur due to the way the Pi draws the screen; to prevent this, simply solder a small jumper wire between pins 4 and 18 on the bonnet. This easy mod tells the bonnet to use PWM to draw the display, resulting in 0 flicker.

After doing this, you'll use this alternate command to launch the script:

sudo python --led-gpio-mapping=adafruit-hat-pwm --led-brightness=60 --led-slowdown-gpio=2

Notice that the --led-gpio-mapping flag is now set to adafruit-hat-pwm instead of adafruit-hat.

Testing panel on boot

Next, we'll want to make sure the scoreboard launches automatically when our Pi boots up and our network device is available. I wrote a separate guide on using Raspberry Pi crontab but here's a recap:

Create our startup script (thanks Tyler!):

nano ~/

Paste the following:

cd /home/pi/nhl-led-scoreboard
until [ $n -ge 10 ]
   python --led-gpio-mapping=adafruit-hat --led-brightness=60 --led-slowdown-gpio=2 && break
   # Uncomment and use this line instead if you did the anti-flicker mod:
   #python --led-gpio-mapping=adafruit-hat-pwm --led-brightness=60 --led-slowdown-gpio=2 && break
   sleep 10

Then, save and exit by pressing CTRL-X, then Y, and then Enter.

Next, make it executable:

chmod +x ~/

Next, run the script on boot:

sudo crontab -e

Add the following command to the bottom:

@reboot /home/pi/ > /home/pi/cron.log 2>&1

Save and exit. Finally, test your change by rebooting your Pi:

sudo reboot

Your scoreboard should now light up after your Pi boots! If it doesn't, you can check cron.log for errors by running cat ~/cron.log.

3D-printed scoreboard housing

If you'd like to add a housing to your scoreboard and have access to a 3D printer, print this amazing model. You'll only need to print the following parts from that model:

  1. raspberry_pi_zero_w_sled_alternate_version.stl
  2. cover_rpi_side.stl
  3. cover_battery_side.stl
  4. p5_panel_frame_rpi_side.stl
  5. p5_panel_frame_battery_side.stl

I printed the housing on my Creality Ender 3. If you're thinking about getting a 3D printer, I highly recommend it.

Panel assembly

Assemble the various panel pieces using M3x8mm bolts and nuts, which you can find on Amazon or at your local hardware store. For detailed assembly instructions, check out this great tutorial written by the model creator.

If the Raspberry Pi sled doesn't fit your screen, you can use a bit of foam tape to secure the Pi to the back of your panel.

If you used a different-sized LED panel (like a 3mm or 4mm pitch panel), you can search Thingiverse for housings that fit your panel. The overall dimensions of the different "pitch" panels are completely different.

Optional power button
The power button fits perfectly in the optional 3D-printed housing.

I added a power button to shut the Pi down safely and boot it up using this Pi power button guide. This is optional but recommended; you always want to shut the Pi down safely to prevent data corruption.

Follow that guide to add your own power button; since the bonnet covers the Raspberry Pi's GPIO header, simply solder the wires (or two pins) to the SCL and GND pins on the bonnet instead.

The button itself lives in the opening on the side of the panel housing.

Final hockey scoreboard photo

This was a very fun, very easy project and a great foray into driving LED panels using a Raspberry Pi. Place your scoreboard on a shelf, give it to a friend, or set it on your desk and never miss another game.

MLB LED scoreboard marquee
There are a lot of possibilities here! This 3D-printed marquee housing was designed by a Cubs fan and uses the MLB-LED-Scoreboard library.

There are a few things I have planned in the immediate future:

Real-time clock countdown functionality

One thing this project is missing is a game clock that counts down in real-time; since it retrieves game data every minute or so, it displays the current time remaining in a static format; it would be great to modify the code to count down in seconds until the next retrieval.

It's important to note this is a new open-source project coded by volunteers; if you're a developer and want to contribute, I created a GitHub issue for this feature.

Installing MLB scoreboard

Once baseball season starts back up, I plan on installing the MLB-LED-Scoreboard library as well! Then, I'll use a button to toggle between the different views. But for now, it's all hockey.

Weather and a clock on off-days

When there's no game, I'd love to see my local weather; the MLB library has this functionality. It would be cool to show this on the pregame screen as well.


I'd like to add a potentiometer (knob) to the side of the display to adjust the panel brightness on-the-fly. Maybe even a light sensor. :)

Other things

This will be an ongoing project that I'll be improving over time—subscribe to me on YouTube or like Howchoo on Facebook to get notified when I do!
