How does it work?

Beam is a LED matrix that can store up to 36 unique frames and play it back at different speeds.  With this amount of storage, you can create different animations or store different lines of text to display.

My Beam doesn't work.  Help!

Here are a few things to try:

  1. Make sure both VHOST+ and 3V3 are plugged in.  These are mandatory.  We have built in level shifters into the Beam, so it will work with 3v3 and 5V Hosts.  
  2. If you're using more than 1 Beam, make sure the Beamcount is updated to the correct number.
