The U9 and U10 products in blue boxes are the smallest box-type controllers in the range listed above. The GU2 is the slimmest and smallest Wall Plate controller in the range above.
For professional installs or integrations, we sometimes integrate these programmable controllers into a complete light control box that features the power supplies and led driver cards. When we do this we often just use the card inside the blue box with no casing.
We also have a tiny, minuature controller available which is likely the smallest programmable DMX controller in the world. Please contact us for more details.
