The conductive pad on the bottom of each button closes a contact underneath when pressed, providing ~3mm of silent travel with a satisfying feel.\n\nThe 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.\n\nKey Features\n\n\n16 Buttons (4×4) – Soft silicone with conductive contact pads\n\n3mm LED Compatible – Each button cavity fits a 3mm LED for backlighting\n\nTileable – Edge-to-edge tiling with correct grid alignment\n\nCuttable – Soft silicone can be trimmed for custom sizes\n\nSilent Operation – ~3mm travel, completely quiet\n\nDurable – Easy to clean with mild soap and water\n\n\nSpecifications\n\n\nButton Size – 10 × 10mm square, 10mm tall\n\nGrid Spacing – 5mm between buttons\n\nTravel – ~3mm\n\nLED Compatibility – 3mm LEDs (5mm will not fit)\n\n\nIdeal For\n\nCustom button panels and macro pads\nAdafruit Trellis projects\nBacklit control interfaces\nMusical instruments and MIDI controllers\n\n\n\nTip: For best backlighting results, use diffused 3mm LEDs with 300mcd or greater brightness.
