You heard that right, no more single-color LEDs, you can now have any color you like under the fantastic rubbery button pads we sell.\u003c\/p\u003e\u003cp\u003eThese 4x4 button pad boards are fully tile-able and communicate over I2C. With 5 address pins, you've got the ability to connect up to 32 together in any arrangement you like. With our trusty seesaw I2C-to-anything chip, you don't even need to manage the NeoPixel driving. That's right! Both the button management and LED driving is completely handled for you all over plain I2C. With both Arduino\/C++ and CircuitPython\/Python library support, you can use these pads with any and all microcontroller or computer boards.\u003c\/p\u003e\u003cp\u003ePerfect for your next cool interface, MIDI instrument, control panel...whatever could benefit from beautiful diffused colorful buttons.
