No longer are you limited to boring two dimensional printed circuit boards that require soldering, but are instead free to let your imagination go wild. Due to the resistivity of this paint, it is best suited to low current applications such as powering LEDs, connecting buttons, creating resistors, or using it as capacitive sensors.

It also works with the Touch Board, Pi Cap, electrical components,  prototyping materials, PCBs, MaKey MaKey and e‐textiles. Why not try using it with the Touch Board or Pi Cap to make touch sensors and switches.
