A soft, squishy 4×4 silicone elastomer keypad with 16 buttons, each designed to fit a 3mm LED for optional backlighting. The conductive pad on the bottom of each button closes a contact underneath when pressed, providing ~3mm of silent travel with a satisfying feel.

The keypads can be tiled edge-to-edge and will align correctly on a grid. The soft silicone can also be cut down to size for custom layouts. Designed to work with the Adafruit Trellis I2C driver board for easy 16-button + 16-LED control, or with your own custom PCB using the provided EagleCAD library.
