PRODUCT DESCRIPTION
The Light Up Board is a touch-controlled, dimmable LED light on a 0.8mm thin circular PCB, which
has six white LEDs and six gold-plated sensor electrodes. With it you can choose between touch,
dimmer or proximity interaction modes and no computer programming is required. The Light Up
Board uses the same MPR121 capacitive sensing chip as the Touch Board but it is even easier to use.
Quickly add light in a difcult to reach spot, demo a lighting control concept, or prototype a design
for an interactive lamp. The Light Up Board is easy to use and is simple to integrate. Use our patent-
pending twist and lock methodv to attach the board to card or plastic, or stick it where you need it
using double-sided tape or adhesive.
The Light Up Board also has a realistic candle light, spin and dice mode. To expand your creative
possibilities still further, you can combine a Light Up Board with Electric Paint and other conductive
materials. The Light Up Board is Micro-USB-powered by most phone-chargers or power banks, so
you can wire it up permanently, or make it portable.
