Expand your Nanoleaf display The Nanoleaf Elements Smarter Kit is a great way to get started creating a mosaic-like light display. It includes a power supply that'll support up to 21 panels, so you can use these expansion packs to build out your system according to your own imagination. Using optional additional power supplies available from Nanoleaf, you can expand your system even further. The controller that came with your base kit can control up to 80 connected panels. Easy setup These add-on panels get their power and Wi-Fi connection directly from your existing Nanoleaf starter kit, so all you have to do is decide on a design for your newly expanded system. The Nanoleaf app lets you preview different panel configurations and virtually project your design on your wall using its built-in Layout Assistant. Try out a bunch of options before you ever unpeel the adhesive backing and install the panels.
