NEW PRODUCT – Silicone Elastomer 4×4 Button Keypad – for 3mm LEDs

1611 Lrg
NEW PRODUCT – Silicone Elastomer 4×4 Button Keypad – for 3mm LEDs. 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 project.

1611Bottom Lrg
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.

1611Side Lrg
On the bottom of each button is a conductive pad ring which can close a properly design contact underneath. We have an EagleCad library which has objects for the buttons and optional LEDs so you can use them in your next PCB design.

Each button is 10mm tall and can fit a 3mm LED inside quite easily. 5mm LEDs are too big, so stick with 3mm here. The LED is optional, having it or not does not affect the ‘action’. but it’s nice to backlight buttons. Diffused LEDs are best, so check out our offerings: the blue, white and red look best, if you’re sourcing your own LEDs go for something with 300mcd or greater brightness. Diffused looks better than not.

Chances are you don’t want to make your own PCB, so pick up an Adafruit Trellis, our tile-able driver which can control 16 LEDs + these 16 buttons over I2C

Check out our github repository for 3D CAD files and an Eagle library with ready-to-go objects

Sign up page, we’re putting these in the store shortly and they’re going to go QUICK!



Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results.
