Adafruit Silicone Elastomer 4x4 Button Keypad - 2 Pack [ADA4021]
So squishy! These silicone elastomer keypads are just waiting for your fingers to press them. Go ahead, squish all you like! (They're durable and easy to clean, just wipe with mild soap and water) These are just like the light up rubber buttons you find on stuff like appliances and tools, but these are open source and easy to integrate into your next NeoTrellis project !
Each button is 10mm x 10mm square and 10mm tall . There is 5mm of grid spacing between the buttons. You can 'tile' the button pads edge-to-edge and they'll grid up correctly. You can also cut the pads down if you like, the silicone is very soft. The way they're molded, they give about 3mm of travel when pressed for a very satisfying feel. They are completely quiet, however.
You get two (2) button pads in this pack so this is the elastomer pack for dressing up your Adafruit NeoTrellis M4 !
