LED tile

What is it

  • Frame containing 6 LED tiles

LED Frame.jpg

  • Controller/PSU "Infiled"


  • 46 individual LED tiles

What are we doing with it?

The space is likely to keep the frame and controller/PSU, and maybe a few extra screens depending on final decision.

Tiles for members

The space keeps the frame and controller, plus possibly a few extra screens (decision tbc), which would leave about 40 for members. Register you interest (before 16th Jan) and keep an eye on the mailing list for update on when the tiles are ready to collect. (update: added members who registered their interest on the mailing list as well)

No more names please, they've all gone

N.B. If you've not done anything with the tile after 3 months please bring it back to the space as someone else may wish to do something with it, don't just let it gather dust in a corner!

LED Specs

The 'tile' contains the matrix of SMDs and the driver ICs and multiplexing to run but you'll need 5v dc and some kind of Pi / Arduino / Nova or Linsn Scancard to control them.

Building a LED wall

On this Mistamud says: You'll need a card called a Scancard. (the brains found inside each and every LED panel): http://www.led-card.com/product_info.php?cPath=24&products_id=314

The signal that goes into the Scancard on Cat5 cable needs to come from a Sender Card: http://www.led-card.com/product_info.php?cPath=23&products_id=15. The signal that goes into a Sender card is good ol' DVI from your laptop.

There's also some info on the progress made with the previous screens here

Michael Margolis thinks that they can be controlled by the SmartMatrix library: https://github.com/pixelmatix/SmartMatrix

and Adafruit have a shield for the teensy with a connector that should(?) work with these tiles : https://www.adafruit.com/products/1902
