Button Pad 4x4 - LED Compatible
This is a translucent silicon rubber button pad with 16 buttons originally inspired by the folks at monome.org. Each button has a hole underneath that accepts either a 3mm or 5mm standard LED. The idea is that you can create a button interface of your choice with the ability to display simple colors under each button. Mainly, we wanted to use our tri-color LEDs to create a full RGB color for each button. 16 button pad can be split up into four, 4 button pads. Each button has a conductive circle backing so that a switch can be created with exposed PCB traces. Button force is between 190 and 2..
